00:02:19,767 --> 00:02:22,900 [ people screaming ] 50 00:02:25,633 --> 00:02:27,500 Narrator: 2007. 51 00:02:27,500 --> 00:02:30,400 A satellite camera captures A shape carved into a mountain 52 00:02:30,400 --> 00:02:35,067 In a remote region Of southwest russia. 53 00:02:35,067 --> 00:02:36,600 Kourounis: I can see an outline, 54 00:02:36,600 --> 00:02:39,400 But I'm not exactly sure What it's meant to be. 55 00:02:39,400 --> 00:02:43,200 It's hard to tell. 56 00:02:43,200 --> 00:02:46,733 The shapes that are forming it Look far more man-made 57 00:02:46,733 --> 00:02:49,967 Compared to something You might get from nature. 58 00:02:49,967 --> 00:02:53,367 Narrator: at first glance, It appears to be a woodland path 59 00:02:53,367 --> 00:02:56,067 Or an off-road track. 60 00:02:56,067 --> 00:03:01,500 But if the image is rotated, A familiar figure emerges. 61 00:03:01,500 --> 00:03:06,500 It looks like It's some kind of horned animal. 62 00:03:06,500 --> 00:03:13,233 It looks like a moose or an elk Or some type of antlered animal. 63 00:03:13,233 --> 00:03:15,467 Narrator: analysis reveals The animal-head shape 64 00:03:15,467 --> 00:03:18,067 Is over 700 feet tall. 65 00:03:18,067 --> 00:03:22,500 It covers an area the size Of 10 football fields. 66 00:03:22,500 --> 00:03:23,867 That's huge. 67 00:03:23,867 --> 00:03:27,867 Imagine trying to take a drawing That you've made 68 00:03:27,867 --> 00:03:31,967 And upscale it to that size And have it still make sense. 69 00:03:31,967 --> 00:03:36,333 Whoever built this went To a lot of trouble. 70 00:03:36,333 --> 00:03:39,167 Narrator: the image comes From the ural mountain range, 71 00:03:39,167 --> 00:03:42,933 100 miles northwest of the Russian border with kazakhstan. 72 00:03:42,933 --> 00:03:46,600 The area is home To the mansi people, 73 00:03:46,600 --> 00:03:51,533 A rugged, nomadic tribe of whom Only a few hundred survive. 74 00:03:51,533 --> 00:03:57,067 But they have lived here For over 800 years. 75 00:03:57,067 --> 00:03:59,667 Before they became subjects Of the russian empire 76 00:03:59,667 --> 00:04:02,400 And forced to convert To christianity, 77 00:04:02,400 --> 00:04:06,600 The mansi performed sacrifices To supernatural beings 78 00:04:06,600 --> 00:04:09,500 And sought the protection Of animal spirits, 79 00:04:09,500 --> 00:04:11,933 The elk and the bear. 80 00:04:11,933 --> 00:04:14,633 To me, The most logical explanation 81 00:04:14,633 --> 00:04:17,400 Is that this elk On the mountainside 82 00:04:17,400 --> 00:04:22,067 Is like a totemic animal That's protecting them 83 00:04:22,067 --> 00:04:24,067 In their everyday life. 84 00:04:24,067 --> 00:04:25,433 It's possible These people would've made 85 00:04:25,433 --> 00:04:28,400 A representation of an animal 86 00:04:28,400 --> 00:04:30,533 Or phenomenon That they feared... 87 00:04:30,533 --> 00:04:32,267 [ bear roars ] 88 00:04:32,267 --> 00:04:35,733 In order to gain protection From it. 89 00:04:35,733 --> 00:04:38,933 Narrator: in 2012, A team of archaeologists venture 90 00:04:38,933 --> 00:04:40,567 Into the russian Forest wilderness 91 00:04:40,567 --> 00:04:44,633 To examine the giant form Up close. 92 00:04:44,633 --> 00:04:48,067 What they find amazes them. 93 00:04:48,067 --> 00:04:50,967 The animalistic figure is Far more sophisticated 94 00:04:50,967 --> 00:04:52,867 Than it appears from space 95 00:04:52,867 --> 00:04:57,433 And far older even Than the ancient mansi tribe. 96 00:04:57,433 --> 00:04:59,800 Horton: when the archaeologists Went and checked it out, 97 00:04:59,800 --> 00:05:03,367 They discovered these aren't Just a few scratches in the soil 98 00:05:03,367 --> 00:05:07,300 But really elaborate, Megalithic structures. 99 00:05:09,333 --> 00:05:12,467 It was a major piece Of civil engineering 100 00:05:12,467 --> 00:05:15,600 With huge boulders being brought 101 00:05:15,600 --> 00:05:18,067 To outline The shape of the animals. 102 00:05:19,767 --> 00:05:22,133 Narrator: among the boulders, Archaeologists find 103 00:05:22,133 --> 00:05:25,767 More than 100 Prehistoric stone tools. 104 00:05:25,767 --> 00:05:28,400 Some of the stone tools found With it suggest 105 00:05:28,400 --> 00:05:31,167 That it's very old indeed 106 00:05:31,167 --> 00:05:32,600 And maybe contemporary 107 00:05:32,600 --> 00:05:37,500 With a whole series Of megalithic cultures. 108 00:05:37,500 --> 00:05:40,067 Narrator: the tools And style of the stonework 109 00:05:40,067 --> 00:05:43,233 Dates the structure To 4,000 b.C. 110 00:05:43,233 --> 00:05:45,600 Put in broad perspective, This is, what, 111 00:05:45,600 --> 00:05:47,833 2,00, 3,000 years older 112 00:05:47,833 --> 00:05:49,933 Than some of The great pyramids of egypt. 113 00:05:53,200 --> 00:05:57,067 Narrator: The local mansi people did not Create this giant carving. 114 00:05:57,067 --> 00:06:02,400 It's the work of a previously Unknown prehistoric people. 115 00:06:02,400 --> 00:06:05,167 When archaeologists dig deeper, 116 00:06:05,167 --> 00:06:08,333 They discover the remains Of ancient fire pits. 117 00:06:08,333 --> 00:06:10,467 The presence Of ancient fire pits 118 00:06:10,467 --> 00:06:12,067 Adds credence to the notion 119 00:06:12,067 --> 00:06:14,633 That this was used For ritual purposes. 120 00:06:14,633 --> 00:06:17,067 [ people chanting indistinctly ] 121 00:06:17,067 --> 00:06:20,567 Geoglyphs would've been The perfect sacred site 122 00:06:20,567 --> 00:06:22,867 For the gathering Of communities. 123 00:06:22,867 --> 00:06:26,067 And within some belief systems, 124 00:06:26,067 --> 00:06:29,133 There would've been Ritual sacrifices. 125 00:06:29,133 --> 00:06:33,200 Narrator: The rituals carried out here Date back to neolithic times. 126 00:06:33,200 --> 00:06:34,967 Bloody shamanistic sacrifices 127 00:06:34,967 --> 00:06:39,067 Were supposed to ward off Evil spirits. 128 00:06:39,067 --> 00:06:41,533 But if this giant Mountainside symbol was meant 129 00:06:41,533 --> 00:06:43,833 To protect its creators, 130 00:06:43,833 --> 00:06:46,500 The question is, "From what?" 131 00:06:49,700 --> 00:06:53,767 According to local legend, A large, prehistoric being, 132 00:06:53,767 --> 00:06:56,067 A survivor From the last ice age, 133 00:06:56,067 --> 00:06:58,067 Still roams these mountains. 134 00:07:01,967 --> 00:07:06,367 Larger than a man, upright But ape-like in appearance, 135 00:07:06,367 --> 00:07:10,167 The russians call This terrifying beast the menk. 136 00:07:10,167 --> 00:07:12,967 People firmly believe That they are there, 137 00:07:12,967 --> 00:07:18,800 And there isn't evidence That they're not. 138 00:07:18,800 --> 00:07:22,067 Narrator: Could the prehistoric animal Carved into the mountainside 139 00:07:22,067 --> 00:07:25,600 Be there to protect the ancients From the legendary menk? 140 00:07:25,600 --> 00:07:28,067 You could speculate That this hill figure 141 00:07:28,067 --> 00:07:33,800 Is to warn off Scary, yeti-like folk. 142 00:07:33,800 --> 00:07:36,900 Narrator: scientists have Dismissed the menk as mythical. 143 00:07:36,900 --> 00:07:39,533 But a menk-like beast Has been blamed by some 144 00:07:39,533 --> 00:07:42,700 For the terrifying events That took place in 1959... 145 00:07:45,933 --> 00:07:47,800 In the very same ural mountains 146 00:07:47,800 --> 00:07:51,833 The prehistoric Animal carving is located. 147 00:07:55,600 --> 00:07:57,700 The dyatlov pass incident talks 148 00:07:57,700 --> 00:08:02,367 About a team Of experienced hikers. 149 00:08:02,367 --> 00:08:08,767 At one point in the expedition, Something went seriously wrong. 150 00:08:08,767 --> 00:08:10,833 Sleeping in their
