It's coming right in. 54 00:02:38,700 --> 00:02:41,000 I'm flying the drone right now with the LiDAR equipment on it. 55 00:02:41,867 --> 00:02:44,967 {\an8}This particular unit is 4k resolution. 56 00:02:46,767 --> 00:02:49,500 I've been scanning the meteorite fault zone 57 00:02:49,667 --> 00:02:51,467 between the open pit and the energy zone. 58 00:02:52,367 --> 00:02:54,467 Ultimately, it'll give me a 4D image, 59 00:02:54,634 --> 00:02:57,200 a very detailed image of this area. 60 00:02:57,367 --> 00:03:00,100 We'll be able to subtract out the vegetation here. 61 00:03:01,300 --> 00:03:03,000 If there's an underground opening here, 62 00:03:03,166 --> 00:03:05,566 this is where it's gonna be. 63 00:03:05,567 --> 00:03:08,567 For the past several weeks, the team has been searching 64 00:03:08,734 --> 00:03:10,900 for an opening to the keyhole chamber 65 00:03:11,066 --> 00:03:13,266 along the meteorite fault zone. 66 00:03:13,433 --> 00:03:15,500 These are doorways into the underground. 67 00:03:15,667 --> 00:03:17,600 It's connected to that keyhole chamber. 68 00:03:17,767 --> 00:03:20,266 I think this place does have a lot of potential. 69 00:03:20,433 --> 00:03:22,999 And after discovering a collapsed opening near 70 00:03:23,000 --> 00:03:24,466 the open pit mine... 71 00:03:24,467 --> 00:03:26,367 This whole thing is a void, man. 72 00:03:27,600 --> 00:03:31,099 ...the team believes they have found an underground void that 73 00:03:31,100 --> 00:03:33,266 connects to the keyhole chamber. 74 00:03:35,367 --> 00:03:39,667 Now, Eric is using enhanced LiDAR to scan one mile 75 00:03:39,834 --> 00:03:42,800 of the fault line to identify other potential openings. 76 00:03:44,166 --> 00:03:46,265 So, this is my final pass here. 77 00:03:46,266 --> 00:03:49,967 I've got it pre-programmed to do about a mile square grid. 78 00:03:51,667 --> 00:03:54,266 Once I'm done here, I'll go back, look at the data, 79 00:03:54,433 --> 00:03:55,766 and find the most compelling spot 80 00:03:55,767 --> 00:03:57,367 where the underground opening will be. 81 00:04:04,066 --> 00:04:06,667 {\an8}And so, I'm just gonna let it run here. 82 00:04:06,834 --> 00:04:11,466 {\an8}The end result is an amazingly detailed high-resolution map. 83 00:04:11,467 --> 00:04:14,999 We can do things like subtract out the vegetation. 84 00:04:15,000 --> 00:04:18,066 And so, what I can actually see is, I can see the geology. 85 00:04:19,100 --> 00:04:21,000 And that allows me to look at features 86 00:04:22,000 --> 00:04:23,700 such as cave openings. 87 00:04:25,767 --> 00:04:28,100 They show up as little anomalies, basically. 88 00:04:29,066 --> 00:04:31,866 And I can pinpoint each of those locations, 89 00:04:31,867 --> 00:04:36,165 get a GPS coordinate on them, and then we can get to them. 90 00:04:36,166 --> 00:04:37,566 So what I'm seeing here is 91 00:04:37,567 --> 00:04:40,266 there's a cave opening right there. 92 00:04:41,667 --> 00:04:43,867 I see another cave opening right there. 93 00:04:46,200 --> 00:04:50,066 Fault zone, there's another one right there. 94 00:04:52,500 --> 00:04:54,100 This is what we need to check out. 95 00:05:03,000 --> 00:05:05,300 {\an8}How's it going, guys. 96 00:05:07,166 --> 00:05:09,000 I've gathered up the fellas today to go over 97 00:05:09,166 --> 00:05:10,666 the LiDAR results that we have, 98 00:05:10,667 --> 00:05:12,700 I'm psyched to hear what Eric has uncovered. 99 00:05:14,266 --> 00:05:17,467 {\an8}I mean, every little clue we find can lead us possibly 100 00:05:17,634 --> 00:05:18,699 {\an8}into another entrance 101 00:05:18,700 --> 00:05:21,400 {\an8}to this underground keyhole cavern system we have. 102 00:05:22,467 --> 00:05:25,867 We got the results of the LiDAR scan here. 103 00:05:26,033 --> 00:05:27,866 I've got some real encouraging signs here. 104 00:05:27,867 --> 00:05:30,600 I'm looking at several intriguing possibilities. 105 00:05:31,667 --> 00:05:33,266 I've got three potential openings 106 00:05:33,433 --> 00:05:35,166 that I want to investigate. 107 00:05:35,333 --> 00:05:37,566 They're all spread across the fault line. 108 00:05:37,567 --> 00:05:40,099 This area here, if you look on the bottom here, 109 00:05:40,100 --> 00:05:41,566 you'll have a lat and long 110 00:05:41,567 --> 00:05:43,400 that is definitely worth looking into. 111 00:05:44,400 --> 00:05:47,000 Eric's scans have located three openings 112 00:05:47,166 --> 00:05:49,866 along the fault line that are large enough to be 113 00:05:49,867 --> 00:05:53,066 potential entrances into the underground void. 114 00:05:53,233 --> 00:05:55,766 All are just south of the open pit mine 115 00:05:55,767 --> 00:05:58,265 and the collapsed opening. 116 00:05:58,266 --> 00:05:59,567 I mean, if you're finding these sites 117 00:05:59,734 --> 00:06:01,800 on the same fault line, that same trend, 118 00:06:01,967 --> 00:06:03,967 {\an8}this is the path that we want to be on 119 00:06:04,133 --> 00:06:05,500 {\an8}and that we want to follow, right here. 120 00:06:05,667 --> 00:06:07,166 {\an8}I mean, that's incredible, Eric. 121 00:06:09,367 --> 00:06:10,367 I mean, we got multiple fronts 122 00:06:10,533 --> 00:06:12,100 that we have to attack here, right? 123 00:06:12,266 --> 00:06:13,165 And each of these sites has 124 00:06:13,166 --> 00:06:15,265 different, unique qualities about them. 125 00:06:15,266 --> 00:06:18,265 I think we should split up and check them all right now. 126 00:06:18,266 --> 00:06:19,700 {\an8}- What do you think? - Yeah. 127 00:06:19,867 --> 00:06:21,266 {\an8}- Yeah. - Agreed. 128 00:06:21,433 --> 00:06:23,266 - Hell yeah. - Let's do this. 129 00:06:23,433 --> 00:06:24,367 Pack up and go. 130 00:06:31,667 --> 00:06:35,900 I can already see a crisscross of more fault right up here. 131 00:06:36,066 --> 00:06:37,700 Let's keep moving. We're almost there. 132 00:06:39,000 --> 00:06:40,367 To investigate the openings 133 00:06:40,533 --> 00:06:42,567 identified on the LiDAR scans... 134 00:06:44,367 --> 00:06:45,367 Right over there. 135 00:06:45,533 --> 00:06:47,999 That'll give us a direct line down. 136 00:06:48,000 --> 00:06:51,266 We're looking just about due north, right up in here. 137 00:06:52,500 --> 00:06:55,800 ...the team will split up into three groups. 138 00:06:55,967 --> 00:06:58,266 Eric will examine the cave to the south. 139 00:06:58,433 --> 00:07:02,400 Chad and Josh will go north, leaving James and Charlie to 140 00:07:02,567 --> 00:07:04,500 inspect the cave to the west. 141 00:07:11,000 --> 00:07:13,600 Yeah, right here, Charles, is where they crisscross. 142 00:07:13,767 --> 00:07:16,566 - The fault line? - Yeah, at the creek. 143 00:07:16,567 --> 00:07:19,265 So we'll go across this way. 144 00:07:19,266 --> 00:07:20,700 Well, this is what we're looking for. 145 00:07:22,367 --> 00:07:23,567 What the hell is this over here? 146 00:07:23,734 --> 00:07:24,667 What is that? 147 00:07:29,600 --> 00:07:31,000 - That's a ear tag. - Oh, man. 148 00:07:33,200 --> 00:07:35,265 Something ripped that cow's ear off. 149 00:07:35,266 --> 00:07:36,900 - That's number 840... - 846? 150 00:07:37,066 --> 00:07:41,766 Number 846.

That's our opening. 167 00:08:32,066 --> 00:08:33,967 That looks large in there. Look at that. 168 00:08:36,066 --> 00:08:37,100 It almost looks like somebody 169 00:08:37,266 --> 00:08:38,800 might have tried covering it up. 170 00:08:41,266 --> 00:08:44,099 Damn, James.
