So what is it? 55 00:04:17,920 --> 00:04:21,120 Even from above, it's hard to get the full picture. 56 00:04:22,880 --> 00:04:26,440 But we have a good idea of the original layout of the site. 57 00:04:27,640 --> 00:04:30,480 And it's like nothing else from the ancient world. 58 00:04:34,680 --> 00:04:38,200 Mound A likely originally stood as high as 100 feet, 59 00:04:39,520 --> 00:04:41,800 anchoring a 43-acre plaza. 60 00:04:42,960 --> 00:04:45,200 With six concentric ridges, 61 00:04:45,280 --> 00:04:49,480 each perhaps as tall as six feet and leveled off at the top 62 00:04:49,560 --> 00:04:53,760 creating a half circle with a diameter of three quarters of a mile, 63 00:04:55,080 --> 00:04:57,240 broken up by a series of aisles, 64 00:04:57,320 --> 00:04:59,280 like some kind of amphitheater. 65 00:05:00,840 --> 00:05:05,440 And scattered nearby are no less than six massive man-made mounds 66 00:05:05,520 --> 00:05:09,080 labeled by archaeologists, simply "A" through "F". 67 00:05:14,760 --> 00:05:16,640 Poverty Point is one of the largest 68 00:05:16,720 --> 00:05:19,160 and most complex ancient sites in North America. 69 00:05:21,080 --> 00:05:25,320 Its oldest sections date back to 3,700 years ago... 70 00:05:26,800 --> 00:05:30,120 long before its builders farmed the land or kept livestock. 71 00:05:32,840 --> 00:05:35,240 And the ancient Americans of Poverty Point 72 00:05:35,320 --> 00:05:37,840 then spent the next 600 years 73 00:05:37,920 --> 00:05:41,080 continuously developing and improving the site. 74 00:05:43,840 --> 00:05:44,840 Why? 75 00:05:48,360 --> 00:05:50,360 No documents or traditions have survived 76 00:05:50,440 --> 00:05:53,240 to tell us what Poverty Point's purpose was. 77 00:05:53,320 --> 00:05:55,400 So archaeologists are left guessing. 78 00:05:57,480 --> 00:06:00,240 Site manager and historian, Mark Brink Jr., 79 00:06:00,320 --> 00:06:03,280 is the first to admit that mainstream archaeology 80 00:06:03,360 --> 00:06:06,920 hasn't been able to confirm much about this mysterious site. 81 00:06:08,120 --> 00:06:10,400 Tell me everything you know about this site. 82 00:06:10,480 --> 00:06:12,720 So Mound A is massive, 83 00:06:12,800 --> 00:06:17,440 the largest mound constructed in the Western Hemisphere at the time, 84 00:06:17,520 --> 00:06:20,920 which shows you that Poverty Point was the center of something truly big. 85 00:06:21,000 --> 00:06:24,000 It suggests, then, a strong motive behind it. 86 00:06:24,080 --> 00:06:26,920 Do you have any thoughts on what that motive could be? 87 00:06:27,000 --> 00:06:28,160 We really don't know. 88 00:06:28,240 --> 00:06:32,120 It was a ceremonial center for some reason, but we don't know yet. 89 00:06:32,200 --> 00:06:34,680 - Can we add the "yet"? - Yeah. 90 00:06:35,280 --> 00:06:36,560 We do have an idea 91 00:06:36,640 --> 00:06:40,080 as to why it was built here and not someplace else, 92 00:06:41,080 --> 00:06:45,920 and it has to do with an even more ancient site about two miles to the south. 93 00:06:46,000 --> 00:06:48,440 As we go south from Poverty Point 94 00:06:48,520 --> 00:06:50,520 we come to a place called Lower Jackson Mound. 95 00:06:50,600 --> 00:06:53,400 And the three principal mounds of Poverty Point 96 00:06:53,480 --> 00:06:57,800 are lined up precisely north-south with Lower Jackson Mound. 97 00:06:58,600 --> 00:07:01,400 And Lower Jackson Mound is much older than Poverty Point. 98 00:07:01,480 --> 00:07:06,640 It dates to 3500 BC, 5,500 years old. 99 00:07:06,720 --> 00:07:11,000 And yet, the makers of Poverty Point were not only aware of it, 100 00:07:11,080 --> 00:07:14,000 but they used it as the anchor of their whole site. 101 00:07:17,320 --> 00:07:19,840 Clearly the ancient builders understood geography 102 00:07:19,920 --> 00:07:22,280 and how to orient structures to true north. 103 00:07:23,520 --> 00:07:26,040 But there's something else going on here at Poverty Point 104 00:07:26,120 --> 00:07:28,840 that archaeologists don't like to acknowledge 105 00:07:29,560 --> 00:07:32,040 encoded in its unique geometry. 106 00:07:33,120 --> 00:07:37,480 You see, the flat horizon all around allows you to observe 107 00:07:37,560 --> 00:07:41,600 the rising and the setting of the Sun and the Moon and the stars. 108 00:07:44,240 --> 00:07:46,680 This is a place for astronomers. 109 00:07:51,960 --> 00:07:54,200 Most of us are not aware of this today. Why should we be? 110 00:07:54,280 --> 00:07:55,640 We live in light-polluted cities. 111 00:07:57,080 --> 00:07:59,000 We can hardly see the skies at all, 112 00:07:59,760 --> 00:08:02,600 but if you were the ancients and you studied the skies, 113 00:08:03,920 --> 00:08:06,000 you would notice this phenomenon. 114 00:08:07,480 --> 00:08:10,000 The Sun has its stopping points on the horizon. 115 00:08:10,080 --> 00:08:11,640 We call them the solstices. 116 00:08:11,720 --> 00:08:13,880 The Sun stops still on the summer solstice, 117 00:08:13,960 --> 00:08:16,200 stays roughly in the same place for two or three days, 118 00:08:16,280 --> 00:08:20,400 and then starts to move back like a pendulum swing along the horizon. 119 00:08:20,480 --> 00:08:22,000 Same on the winter solstice. 120 00:08:25,560 --> 00:08:30,000 Archaeoastronomer William Romain discovered that these important dates, 121 00:08:30,080 --> 00:08:34,800 the solstices, respectively the longest and shortest days of the year, 122 00:08:34,880 --> 00:08:36,880 were actually marked at Poverty Point 123 00:08:36,960 --> 00:08:39,720 by a skillfully designed system of alignments. 124 00:08:43,720 --> 00:08:46,640 If you stand at the eastern edge of the oval space 125 00:08:46,720 --> 00:08:48,440 at the heart of the plaza, 126 00:08:48,520 --> 00:08:52,800 the summer solstice sunset falls directly in line with Mound B, 127 00:08:52,880 --> 00:08:54,080 the oldest mound. 128 00:08:55,440 --> 00:08:57,160 And from the same vantage point, 129 00:08:57,240 --> 00:09:01,480 the winter solstice sunset falls directly behind Mound E. 130 00:09:02,760 --> 00:09:05,640 Move over to the western edge of that same inner oval, 131 00:09:05,720 --> 00:09:10,480 and you'll find that the summer solstice Sun rises directly over Mound C, 132 00:09:11,480 --> 00:09:15,400 while the winter solstice Sun rises directly over Mound D. 133 00:09:17,560 --> 00:09:21,400 And if you gaze directly west through the center of the plaza 134 00:09:21,480 --> 00:09:23,600 on either the spring or fall equinox, 135 00:09:24,760 --> 00:09:28,000 the Sun appears to roll down the northern edge of Mound A 136 00:09:28,080 --> 00:09:30,160 before sinking below the horizon. 137 00:09:36,560 --> 00:09:38,960 Poverty Point may have more intriguing structures 138 00:09:39,040 --> 00:09:41,400 designed to track changes in the sky. 139 00:09:42,640 --> 00:09:43,960 In one corner of the site, 140 00:09:44,040 --> 00:09:47,200 archaeologists found a large circle of holes 141 00:09:49,320 --> 00:09:51,760 marked today by restored white posts. 142 00:09:53,120 --> 00:09:56,960 We don't know how tall the original posts in those holes would have been, 143 00:09:57,800 --> 00:10:00,320 but in its overall conception and design, 144 00:10:00,400 --> 00:10:05,720 it reminds me of the prehistoric Woodhenge excavated near Stonehenge in England. 145 00:10:07,200 --> 00:10:12,400 What's unique about Poverty Point is how many woodhenges it boasts. 146 00:10:13,840 --> 00:10:16,160 These circles, how many of them are there here? 147 00:10:16,760 --> 00:10:19,600 Well, there's probably at least 40 of them. 148 00:10:20,560 --> 00:10:22,160 Scale? Across... 149 00:10:22,240 --> 00:10:25,560 So, some of them are pretty small, maybe 60 feet in diameter, 150 00:10:25,640 --> 00:10:28,640 some are larger, 200 or more feet in diameter, 151 00:10:29,280 --> 00:10:32,000 but the dates on these vary wildly. 152 00:10:33,880 --> 00:10:36,560 [Graham] They were created over the course of hundreds of years, 153 00:10:37,240 --> 00:10:40,080 spanning generations of ancient Americans, 154 00:10:40,160 --> 00:10:43,240 who kept tweaking their position and size over time. 155 00:10:44,920 --> 00:10:47,520 I'm reminded of Malta where the megalith builders 156 00:10:47,600 --> 00:10:49,840 kept changing the orientation of their temples 157 00:10:49,920 --> 00:10:54,400 to face the star Sirius, culminating with Ġgantija. 158 00:10:55,560 --> 00:10:57,760 And of Göbekli Tepe in Turkey 159 00:10:57,840 --> 00:10:59,880 where the ancients built a series of temples 160 00:10:59,960 --> 00:11:02,560 over a period of about a thousand years, 161 00:11:02,640 --> 00:11:06,080 also, I believe, to track the movement of the stars. 162 00:11:07,720 --> 00:11:10,200 These are all massive projects, 163 00:11:10,280 --> 00:11:12,760 featuring structures repeatedly rebuilt 164 00:11:12,840 --> 00:11:16,440 and shifted in their orientation over generations. 165 00:11:17,560 --> 00:11:20,600 Could the multiple post circles of Poverty Point 166 00:11:20,680 --> 00:11:23,640 also have been designed to track something in the heavens? 167 00:11:25,920 --> 00:11:28,880 Sophisticated knowledge, true science 168 00:11:28,960 --> 00:11:32,040 is evidenced by the geometry and the astronomy of the site. 169 00:11:33,680 --> 00:11:36,360 Yet mainstream archaeologists are reluctant 170 00:11:36,440 --> 00:11:40,120 to recognize astronomy of any kind in Poverty Point's wood circles. 171 00:11:42,600 --> 00:11:45,000 - Here, I don't think they make sense. - Mmm-hmm. 172 00:11:45,080 --> 00:11:47,920 Why should the people who lived here and created this place, 173 00:11:48,000 --> 00:11:50,200 why should they not have been interested in the sky? 174 00:11:50,280 --> 00:11:51,800 - I'm not saying they weren't. - No. 175 00:11:51,880 --> 00:11:53,120 I bet they were. 176 00:11:53,200 --> 00:11:55,360 Okay. So what do you think the circles were used for? 177 00:11:56,200 --> 00:11:57,840 We don't know. We don't know yet 178 00:11:57,920 --> 00:11:59,920 if they were used for astronomy purposes or not. 179 00:12:00,000 --> 00:12:01,000 [Graham] Yeah. 180 00:12:02,640 --> 00:12:05,640 Ancient cultures were very fixated upon the sky. 181 00:12:07,040 --> 00:12:09,400 That notion isn't in itself disputed, 182 00:12:09,480 --> 00:12:11,640 but archaeology tends to regard it as irrelevant. 183 00:12:12,600 --> 00:12:14,560 I think that the reason is, in part, 184 00:12:14,640 --> 00:12:18,160 because most archaeologists just don't understand astronomy at all. 185 00:12:18,240 --> 00:12:20,040 It's not what they've been taught to do, 186 00:12:20,120 --> 00:12:22,560 and secondly, they regard it as an intrusion 187 00:12:22,640 --> 00:12:26,000 into their domain by outsiders. 188 00:12:30,080 --> 00:12:33,200 I'm not claiming that Poverty Point was created 189 00:12:33,280 --> 00:12:36,160 by the lost advanced civilization I'm looking for. 190 00:12:38,080 --> 00:12:40,280 But I'm interested in the origins 191 00:12:40,360 --> 00:12:42,800 of the sophisticated astronomy and geometry 192 00:12:42,880 --> 00:12:44,200 that were deployed here. 193 00:12:45,800 --> 00:12:48,480 There's evidence that advanced architectural, 194 00:12:48,560 --> 00:12:53,640 Earth-measuring and astronomical knowledge was inherited from earlier times, 195 00:12:53,720 --> 00:12:57,280 but inherited from whom and how much earlier? 196 00:12:59,880 --> 00:13:02,160 I'm not saying the ancient Americans living here 197 00:13:02,240 --> 00:13:04,920 weren't capable of discovering and incorporating 198 00:13:05,000 --> 00:13:08,960 these astronomical observations into their sites by themselves. 199 00:13:09,360 --> 00:13:10,520 On the contrary. 200 00:13:11,160 --> 00:13:12,440 I think we've passed the point 201 00:13:12,520 --> 00:13:15,400 where we should regard the Native American cultures 202 00:13:15,480 --> 00:13:17,160 as simply hunter-gatherers. 203 00:13:17,240 --> 00:13:21,000 They were much more complicated than that and much more sophisticated. 204 00:13:23,200 --> 00:13:26,160 And their vision of Earth's place in the cosmos 205 00:13:26,240 --> 00:13:28,600 expressed by the alignments at Poverty Point 206 00:13:28,680 --> 00:13:30,920 is essentially the same vision 207 00:13:31,000 --> 00:13:34,440 that we've seen in other ancient sites around the world, 208 00:13:34,520 --> 00:13:36,440 sharing the same focus 209 00:13:36,520 --> 00:13:39,000 on the sacred connection between Earth and sky. 210 00:13:45,760 --> 00:13:49,120 Poverty Point is just one of 800 Mound Builder sites 211 00:13:49,800 --> 00:13:52,280 surviving across the state of Louisiana. 212 00:13:53,280 --> 00:13:55,280 While in North America as a whole, 213 00:13:55,360 --> 00:13:59,320 out of an original estimated total of one million mounds, 214 00:13:59,400 --> 00:14:01,960 around 100,000 still remain. 215 00:14:04,120 --> 00:14:08,600 Amongst these, the most spectacular example of a mound 216 00:14:08,680 --> 00:14:11,400 expressing the sacred connection between Earth and sky, 217 00:14:12,320 --> 00:14:17,920 lies about 600 miles to the northeast of Poverty Point in Ohio, 218 00:14:18,960 --> 00:14:22,520 a site that may just hold the key to understanding what happened 219 00:14:22,600 --> 00:14:25,240 to the lost civilization I've been searching for. 220 00:14:28,280 --> 00:14:30,560 Perched atop a densely forested ridge 221 00:14:31,640 --> 00:14:34,520 lies a stunning example of an effigy mound. 222 00:14:36,800 --> 00:14:40,520 A gigantic earthwork shaped into the form of a living creature. 223 00:14:42,400 --> 00:14:45,560 In this case, a 400-meter-long snake. 224 00:14:48,080 --> 00:14:50,200 It's called Serpent Mound. 225 00:14:52,440 --> 00:14:54,400 Starting from its coiled tail, 226 00:14:54,480 --> 00:14:57,320 seven bends in its body wind their way to the head, 227 00:14:58,600 --> 00:15:03,320 where gaping jaws appear about to engulf a separate oval earthwork. 228 00:15:06,040 --> 00:15:09,600 Even from the air, it's hard to make out all the detail. 229 00:15:10,480 --> 00:15:14,920 But by taking into account new discoveries about its original construction 230 00:15:15,000 --> 00:15:16,480 and stripping away the trees, 231 00:15:17,120 --> 00:15:20,480 we can reveal what the effigy would have looked like in its prime. 232 00:15:25,440 --> 00:15:28,360 Serpent Mound extends more than quarter of a mile 233 00:15:28,440 --> 00:15:30,200 from its jaws in the northwest 234 00:15:30,280 --> 00:15:33,280 to its tail on the southwestern corner of the hilltop. 235 00:15:36,480 --> 00:15:40,200 Originally, there was a circle of standing stones by the head, 236 00:15:40,280 --> 00:15:41,600 function unknown. 237 00:15:43,080 --> 00:15:46,880 And just behind the head, two decorative extensions, 238 00:15:46,960 --> 00:15:48,840 function, likewise, unknown. 239 00:15:55,880 --> 00:15:59,320 Serpent Mound is a remarkable, graceful structure, 240 00:15:59,400 --> 00:16:02,440 one that instills wonder in those who visit. 241 00:16:03,800 --> 00:16:06,720 It's clearly an ancient and mysterious place. 242 00:16:06,800 --> 00:16:09,320 But who built the huge effigy, and why? 243 00:16:12,360 --> 00:16:17,240 The sign of the site will tell you it was built around 1000 AD 244 00:16:17,320 --> 00:16:21,120 by an indigenous people referred to as the Fort Ancient Culture. 245 00:16:22,680 --> 00:16:27,360 But the sign, like so many of these historical markers, is wrong. 246 00:16:28,880 --> 00:16:33,080 Truth is that nobody really knows how old Serpent Mound is. 247 00:16:35,200 --> 00:16:37,200 That date of 1000 AD 248 00:16:37,280 --> 00:16:40,240 was based on just two of the organic samples 249 00:16:40,320 --> 00:16:43,760 taken from parts of the mound that may have been later reconstructed, 250 00:16:45,280 --> 00:16:49,280 because another archaeological survey found samples from the serpent's base 251 00:16:49,360 --> 00:16:52,840 dating back to 321 BC. 252 00:16:54,480 --> 00:16:56,680 The evidence that Serpent Mound was 253 00:16:56,760 --> 00:16:59,640 the subject of a restoration is very clear. 254 00:16:59,720 --> 00:17:03,280 I suggest that these restorations go back deep into the past. 255 00:17:05,040 --> 00:17:08,200 There's just one problem with investigating my theory. 256 00:17:09,079 --> 00:17:13,319 The administrators of Serpent Mound have decided to ban me. 257 00:17:15,800 --> 00:17:20,000 We've made repeated efforts to get permission to film here, 258 00:17:20,079 --> 00:17:22,079 but they denied us that permission. 259 00:17:24,200 --> 00:17:29,200 On what I regard as ideological and indeed rather personal grounds, 260 00:17:29,280 --> 00:17:31,160 let me read from their email. 261 00:17:33,079 --> 00:17:34,600 "Our role is to ensure that 262 00:17:34,680 --> 00:17:37,240 Serpent Mound's integrity and preservation, 263 00:17:37,320 --> 00:17:38,360 both physically 264 00:17:38,440 --> 00:17:41,520 and in its historical interpretation, are maintained." 265 00:17:42,480 --> 00:17:47,200 "Because the presenter of this series, Graham Hancock, 266 00:17:47,280 --> 00:17:51,040 proposes a theory and story that do not align 267 00:17:51,120 --> 00:17:54,880 with what we know to be true about Serpent Mound, 268 00:17:54,960 --> 00:17:57,480 your request is declined." 269 00:18:00,280 --> 00:18:05,440 A correct word for this so-called mission to protect the interpretation of the site 270 00:18:05,520 --> 00:18:07,920 is, of course, censorship. 271 00:18:08,000 --> 00:18:10,440 And what more effective way 272 00:18:10,520 --> 00:18:16,360 for archaeologists to censor and restrain and crush opposing views 273 00:18:16,440 --> 00:18:20,080 than to deny access to archaeological sites? 274 00:18:21,840 --> 00:18:24,520 It's by no means the first time this has happened. 275 00:18:24,600 --> 00:18:29,040 This unfortunately is systematic and consistent behavior 276 00:18:29,120 --> 00:18:30,200 amongst archaeologists. 277 00:18:30,280 --> 00:18:32,120 They do practice censorship. 278 00:18:32,200 --> 00:18:37,560 They practice censorship by ridiculing and insulting alternative ideas. 279 00:18:39,760 --> 00:18:43,040 So what exactly is it in this theory of mine 280 00:18:43,120 --> 00:18:45,360 that's deemed so objectionable? 281 00:18:46,840 --> 00:18:49,800 Quite simply, it's because I dare to suggest 282 00:18:49,880 --> 00:18:53,240 that the idea behind the design of Serpent Mound 283 00:18:53,320 --> 00:18:57,480 goes back to a time much earlier than 300 BC, 284 00:18:58,640 --> 00:19:03,200 more than 10,000 years earlier to the end of the last Ice Age. 285 00:19:05,200 --> 00:19:10,960 And for me, the proof of this lies in one of its most stunning attributes, 286 00:19:11,040 --> 00:19:14,360 one that mainstream archaeologists don't like to acknowledge. 287 00:19:15,000 --> 00:19:17,880 Because again, it involves the sky. 288 00:19:19,960 --> 00:19:24,960 If you overfly Serpent Mound on the summer solstice around June 21st, 289 00:19:25,040 --> 00:19:27,800 you'll immediately notice that the jaws of the serpent 290 00:19:27,880 --> 00:19:32,120 are aligned almost directly to the point where the Sun sets. 291 00:19:34,880 --> 00:19:38,880 So this is what happens at sunset on the summer solstice. 292 00:19:38,960 --> 00:19:42,680 You see the head of the serpent, it seems to be seeking out the Sun, 293 00:19:42,760 --> 00:19:45,760 and then as the Sun begins to go down, you get it more clearly, 294 00:19:45,840 --> 00:19:49,520 this beautiful alignment between Earth and sky, 295 00:19:49,600 --> 00:19:52,360 then the majesty of the site just overwhelms you. 296 00:19:54,320 --> 00:19:57,440 It's obvious to anybody today 297 00:19:57,520 --> 00:20:01,000 that that is what the head of the great serpent is pointing at. 298 00:20:01,600 --> 00:20:06,400 But that idea was ignored and rejected by archaeology for a very long time. 299 00:20:07,280 --> 00:20:09,960 The organization, which runs the site, 300 00:20:10,040 --> 00:20:13,800 has allowed an enormous number of trees to grow up around the head of the serpent. 301 00:20:13,880 --> 00:20:17,000 I think they believe it provides shade to tourists. 302 00:20:17,080 --> 00:20:20,440 But what it does is it limits that massive impact 303 00:20:20,520 --> 00:20:23,800 of seeing the head of the serpent pointing directly at the setting Sun. 304 00:20:28,080 --> 00:20:32,040 Jeff Wilson, who owns much of the property next to the ancient effigy, 305 00:20:32,120 --> 00:20:36,080 is the president of an independent group called The Friends of Serpent Mound, 306 00:20:37,160 --> 00:20:41,800 dedicated to preserving and promoting this and other Native American sites. 307 00:20:43,000 --> 00:20:46,160 Clearly Serpent Mound is very important to you. 308 00:20:46,240 --> 00:20:48,440 Yes, it's very personal to me. 309 00:20:48,520 --> 00:20:52,400 It's one of the most spiritual places I've ever visited. 310 00:20:52,480 --> 00:20:53,800 It's a sacred place. 311 00:20:53,880 --> 00:20:55,200 When you encounter it, 312 00:20:55,280 --> 00:20:59,440 you walk away feeling changed by the experience when you come here. 313 00:21:02,960 --> 00:21:06,160 It's the most amazing archaeoastronomy site in North America, 314 00:21:06,240 --> 00:21:07,240 - bar none. - Yes. 315 00:21:09,160 --> 00:21:12,960 What makes it so is the recent confirmation that the Mound Builders 316 00:21:13,040 --> 00:21:16,920 cleverly incorporated a whole series of sky ground alignments 317 00:21:17,000 --> 00:21:18,640 into Serpent Mound's design. 318 00:21:22,600 --> 00:21:25,040 The center of the second bend behind the head 319 00:21:25,120 --> 00:21:28,880 points eastward to where the Sun rises on the summer solstice, 320 00:21:31,000 --> 00:21:32,960 and the center of the following bend 321 00:21:33,040 --> 00:21:36,440 targets the sunrise on the spring and fall equinoxes 322 00:21:36,520 --> 00:21:39,080 when night and day are of equal length. 323 00:21:41,440 --> 00:21:43,480 While the center of the final bend 324 00:21:43,560 --> 00:21:46,800 is aimed where the Sun rises on the winter solstice, 325 00:21:46,880 --> 00:21:48,760 the shortest day of the year. 326 00:21:50,320 --> 00:21:52,880 As for that intricately coiled tail, 327 00:21:53,600 --> 00:21:56,840 if you draw a straight line from its exact center 328 00:21:56,920 --> 00:21:59,040 through the hinge of the serpent's jaws, 329 00:21:59,120 --> 00:22:03,400 you'll find it's precisely oriented to true astronomical north. 330 00:22:07,280 --> 00:22:10,240 To construct it and to figure out 331 00:22:10,320 --> 00:22:14,280 where all these astronomical alignments that are incorporated into its design 332 00:22:14,360 --> 00:22:16,480 is just an amazing sheer work of genius... 333 00:22:16,560 --> 00:22:17,840 It's a work of genius, yeah. 334 00:22:17,920 --> 00:22:19,560 ...from the prehistoric Native Americans. 335 00:22:19,600 --> 00:22:23,160 Yeah. And that genius is easily overlooked, actually. 336 00:22:23,240 --> 00:22:26,560 Is archaeology taking the astronomy of this site seriously? 337 00:22:26,640 --> 00:22:29,000 Are enough archaeologists taking it seriously? 338 00:22:29,080 --> 00:22:31,080 I don't think so, no. 339 00:22:31,160 --> 00:22:32,360 Um... 340 00:22:32,440 --> 00:22:37,280 There's very few people that even pay attention to it or consider it. 341 00:22:41,800 --> 00:22:45,000 It's as though mainstream archaeologists want us to believe 342 00:22:45,080 --> 00:22:48,760 that all these astronomical alignments happen by accident. 343 00:22:50,200 --> 00:22:55,200 I think it's fair to say that there were people in ancient Native America 344 00:22:55,280 --> 00:22:59,760 with advanced surveying, geometrical and astronomical skills, 345 00:22:59,840 --> 00:23:03,200 and they put those skills to work in the creation of enormous monuments, 346 00:23:03,280 --> 00:23:06,640 most of which have tragically been swept away. 347 00:23:08,560 --> 00:23:13,760 These precise solar alignments manifested on such a gigantic scale 348 00:23:13,840 --> 00:23:16,760 represent an extraordinary achievement for hunter-gatherers 349 00:23:16,840 --> 00:23:18,880 living in the 3rd century BC. 350 00:23:20,440 --> 00:23:24,080 But there's evidence suggesting that the ridge where Serpent Mound sits 351 00:23:24,160 --> 00:23:27,920 was considered sacred for thousands of years before that. 352 00:23:29,600 --> 00:23:33,360 Every single culture that ever existed here, 353 00:23:33,440 --> 00:23:37,880 dating back to the last Ice Age, left cultural remains at Serpent Mound. 354 00:23:37,960 --> 00:23:41,080 What it says to me, this continuous human presence here, 355 00:23:41,760 --> 00:23:45,600 it kind of suggests to me that the site's been sacred for a very long time. 356 00:23:45,680 --> 00:23:46,520 Right. 357 00:23:46,600 --> 00:23:48,760 It seems to me that should be taken into account 358 00:23:48,840 --> 00:23:50,520 in the archaeological narrative. 359 00:23:50,600 --> 00:23:52,640 It should be part of the story of Serpent Mound. 360 00:23:52,720 --> 00:23:53,720 Yes. 361 00:23:56,520 --> 00:24:00,360 Archaeologists have been wrong before and they could be wrong again. 362 00:24:00,960 --> 00:24:05,720 All in all, it's obvious that the origins of Serpent Mound are complicated. 363 00:24:07,080 --> 00:24:12,080 What if 321 BC doesn't mark the year of Serpent Mound's construction, 364 00:24:12,760 --> 00:24:15,320 but one of its many reconstructions? 365 00:24:17,600 --> 00:24:20,560 Let's not forget we're dealing with a serpent here, 366 00:24:20,640 --> 00:24:24,880 and that serpents are creatures renowned for their ability to change their skin. 367 00:24:26,800 --> 00:24:31,200 It's a possibility actually suggested by Serpent Mound's unique alignment. 368 00:24:32,080 --> 00:24:34,800 You see, it isn't quite perfect. 369 00:24:36,920 --> 00:24:40,480 Today the summer solstice Sun, as viewed from Serpent Mound, 370 00:24:40,560 --> 00:24:44,680 actually sets about two degrees off the exact center of the jaws. 371 00:24:45,840 --> 00:24:47,880 Seems close enough to the naked eye. 372 00:24:49,840 --> 00:24:54,080 But it's hard to believe that the people who conceived of and created 373 00:24:54,160 --> 00:24:58,240 this sophisticated effigy mound, tracking all those calendar moments, 374 00:24:58,880 --> 00:25:02,840 would go to all this trouble and not get it exactly right. 375 00:25:04,560 --> 00:25:06,440 I think they did get it right. 376 00:25:08,280 --> 00:25:12,240 It all has to do with the way the Earth shifts on its axis over the millennia. 377 00:25:13,800 --> 00:25:16,240 In a phenomenon long known to astronomers 378 00:25:16,840 --> 00:25:20,120 who refer to it as the obliquity of the ecliptic. 379 00:25:21,080 --> 00:25:22,440 To put it in simple terms, 380 00:25:22,520 --> 00:25:24,720 the Earth, as we know, is tilted on its axis, 381 00:25:24,800 --> 00:25:27,120 but that tilt is not fixed and constant. 382 00:25:27,200 --> 00:25:30,680 It changes over a 41,000-year cycle. 383 00:25:30,760 --> 00:25:33,520 It changes roughly two-and-a-half degrees over that cycle. 384 00:25:33,600 --> 00:25:35,120 It nods back and forward, 385 00:25:35,800 --> 00:25:40,040 and that affects the rising position of the Sun on the summer solstice. 386 00:25:42,640 --> 00:25:44,720 Instead of asking why the serpent's jaws 387 00:25:44,800 --> 00:25:48,080 aren't perfectly aligned to the summer solstice sunset, 388 00:25:49,800 --> 00:25:52,080 what if we asked a different question? 389 00:25:53,360 --> 00:25:57,720 When, if one takes into account this obliquity of the ecliptic, 390 00:25:57,800 --> 00:26:01,680 did the gaping jaws and the setting Sun line up perfectly? 391 00:26:05,800 --> 00:26:08,200 Turns out it wasn't a thousand years ago, 392 00:26:08,280 --> 00:26:10,680 or even 2,300 years ago, 393 00:26:10,760 --> 00:26:14,240 when archaeologists insist Serpent Mound was first constructed. 394 00:26:15,200 --> 00:26:18,800 The serpent's mouth was exactly centered on the Sun 395 00:26:18,880 --> 00:26:21,920 around 12,800 years ago 396 00:26:23,040 --> 00:26:24,800 at the end of the last Ice Age, 397 00:26:27,280 --> 00:26:29,080 when the ridge on which the serpent was built 398 00:26:29,160 --> 00:26:33,440 itself occupied an extraordinarily significant spot. 399 00:26:37,840 --> 00:26:42,720 At the very peak of the Ice Age, around 20,000 years ago, 400 00:26:42,800 --> 00:26:48,000 much of North America was covered by an immense ice cap over a mile deep. 401 00:26:51,040 --> 00:26:55,600 Today, Ohio's Serpent Mound Valley is a forest-covered wilderness, 402 00:26:56,200 --> 00:26:58,320 but let's not look at it as it is now. 403 00:26:59,200 --> 00:27:02,720 Let's look at it as it was during the last Ice Age. 404 00:27:04,120 --> 00:27:08,080 This very valley, where the great serpent was constructed, 405 00:27:08,160 --> 00:27:12,560 actually marks the furthest south that the North American ice sheet reached. 406 00:27:13,760 --> 00:27:17,240 The giant ice cliffs rising just by this ridge 407 00:27:17,320 --> 00:27:20,240 would have looked like something out of a fantasy novel. 408 00:27:21,400 --> 00:27:23,720 To the people who lived through this period, 409 00:27:23,800 --> 00:27:27,360 it must have seemed that some benign magical power was at work. 410 00:27:29,240 --> 00:27:32,800 But any celebration of the halt of the ice would have been short-lived, 411 00:27:34,160 --> 00:27:37,280 because sometime around 12,800 years ago, 412 00:27:37,960 --> 00:27:41,720 when the serpent was perfectly aligned with the summer solstice, 413 00:27:41,800 --> 00:27:45,080 something huge was happening all over the planet. 414 00:27:45,640 --> 00:27:46,480 [thunderclap] 415 00:27:46,560 --> 00:27:48,760 Something apocalyptic 416 00:27:50,560 --> 00:27:52,240 called the Younger Dryas. 417 00:27:53,600 --> 00:27:57,680 It was a period of radical climate change and rising sea levels. 418 00:27:59,800 --> 00:28:02,480 Humanity survived, but barely. 419 00:28:09,400 --> 00:28:14,320 I find it intriguing, by means of its alignment to the summer solstice sunset, 420 00:28:15,080 --> 00:28:19,800 that Serpent Mound serves as a signpost, a date stamp, 421 00:28:19,880 --> 00:28:24,440 drawing our attention to the skies of 12,800 years ago, 422 00:28:24,520 --> 00:28:27,960 a time when we know there was a global cataclysm 423 00:28:28,040 --> 00:28:31,000 big enough to have destroyed an advanced civilization. 424 00:28:34,600 --> 00:28:37,000 Again, I'm reminded of Göbekli Tepe, 425 00:28:37,080 --> 00:28:40,760 where figures of creatures carved into one of the most spectacular pillars 426 00:28:41,400 --> 00:28:45,160 seem to depict the position of the stars at the summer solstice 427 00:28:45,240 --> 00:28:47,240 during the time of the Younger Dryas. 428 00:28:48,920 --> 00:28:53,200 It's no accident in my view that the serpent's solstitial alignment 429 00:28:53,280 --> 00:28:56,400 also speaks to that same cataclysmic epoch. 430 00:28:57,840 --> 00:28:59,320 But why a serpent? 431 00:29:04,360 --> 00:29:06,120 Of the greatest relevance, I think, 432 00:29:06,200 --> 00:29:08,720 are numerous Native American myths and traditions 433 00:29:08,800 --> 00:29:13,960 in which giant serpents are directly associated with cataclysmic Earth changes. 434 00:29:16,760 --> 00:29:19,120 There's an ancient legend of the Iroquois 435 00:29:19,200 --> 00:29:23,520 whose domain at the height of their power extended deep into Ohio. 436 00:29:23,600 --> 00:29:27,440 The villain of the legend is a giant horned serpent. 437 00:29:30,880 --> 00:29:34,520 Long ago, a village was plagued by a great serpent 438 00:29:34,600 --> 00:29:36,240 who dwelt in a nearby lake. 439 00:29:37,080 --> 00:29:41,520 So the great spirit in the sky sent down a hero to defeat him. 440 00:29:43,240 --> 00:29:47,080 In a vicious battle, bolts of lightning struck the serpent, 441 00:29:48,440 --> 00:29:52,000 the sound shook the Earth, and the flashes were so bright 442 00:29:52,080 --> 00:29:56,760 that the people shielded their eyes, covered their ears, and hid in fear. 443 00:29:58,520 --> 00:30:02,320 The very constellations were dislodged from the night sky 444 00:30:02,400 --> 00:30:07,240 and came crashing to Earth with a ferocious blast and scorching heat. 445 00:30:07,320 --> 00:30:10,720 One star fell into the lake, wounding the horned serpent. 446 00:30:13,040 --> 00:30:15,920 As the great serpent thrashed its tail in pain, 447 00:30:16,000 --> 00:30:17,600 it sent 100-foot waves 448 00:30:17,680 --> 00:30:20,840 crashing through the valleys in a series of colossal floods. 449 00:30:22,600 --> 00:30:26,800 Most of the tribe didn't survive, but the serpent was driven away. 450 00:30:30,840 --> 00:30:35,600 We've already seen such serpent imagery in ancient monuments all over the world. 451 00:30:37,000 --> 00:30:38,280 On the temples in Mexico, 452 00:30:38,360 --> 00:30:41,760 dedicated to Quetzalcoatl, the feathered serpent, 453 00:30:42,360 --> 00:30:45,480 carved into the temple of Ġgantija on Malta, 454 00:30:46,200 --> 00:30:49,800 and raining down from the skies on the pillars of Göbekli Tepe. 455 00:30:51,160 --> 00:30:52,880 It's a powerful symbol 456 00:30:52,960 --> 00:30:56,240 found at sites that invite us to look to the heavens. 457 00:30:57,680 --> 00:30:58,760 Why? 458 00:31:00,760 --> 00:31:04,960 I think this Iroquois legend has more than a kernel of truth to it. 459 00:31:05,040 --> 00:31:06,440 Perhaps the stars, 460 00:31:06,520 --> 00:31:10,160 or something resembling stars, did fall to Earth. 461 00:31:10,240 --> 00:31:12,480 Perhaps there was great flooding afterwards, 462 00:31:12,560 --> 00:31:16,440 part of those earthshaking cataclysms of the Younger Dryas. 463 00:31:18,560 --> 00:31:20,640 If the original version of Serpent Mound 464 00:31:20,720 --> 00:31:25,240 was designed sometime around the end of the last Ice Age, as I believe, 465 00:31:25,320 --> 00:31:29,600 then perhaps it was intended to carry a message to the future, 466 00:31:29,680 --> 00:31:34,280 a warning even, as to what caused that apocalyptic series of events 467 00:31:34,360 --> 00:31:36,600 around 12,800 years ago, 468 00:31:37,240 --> 00:31:42,000 a warning to look to the heavens for stars falling from the sky. 469 00:31:46,080 --> 00:31:48,040 A quarter of the way around the Earth, 470 00:31:48,120 --> 00:31:51,640 there's evidence that other ancient peoples also lived in terror 471 00:31:51,720 --> 00:31:53,560 of just such a threat from above, 472 00:31:54,520 --> 00:31:56,720 and took steps to protect themselves 473 00:31:56,800 --> 00:32:00,360 deep in the heart of Cappadocia in modern-day Turkey, 474 00:32:01,120 --> 00:32:03,080 which is where I'm heading next.
