What the Canadian Shield Has Been Hiding for 4 Billion Years

#Canada #HiddenCanada #CanadianGeography Beneath half of Canada lies rock that was already ancient when the first fish swam. Most of the country flies over it and calls it nothing: bush, lakes, empty space. But the ground here is still rising, part of it pulls on you more weakly than the rest of the planet, and deep inside one mine there is water that has not seen daylight for two billion years. These are 30 things the Canadian Shield is hiding: a silver mine drowned under Lake Superior, whales buried under Ottawa farmland, diamonds under drained Arctic lakes, the hottest rock ever found, the crystal-clear Pingualuit crater and the oldest firmly dated rock on Earth. None of it is secret. It just never made it into the story Canada tells about itself. 00:00 Intro 00:56 No. 30 The ground that stands back up 01:46 No. 29 The dent in gravity 02:32 No. 28 The bridge of granite 03:25 No. 27 The panther under the water 04:20 No. 26 The canyon that kept the Ice Age 05:16 No. 25 The giant who kept a secret 06:17 No. 24 The ocean that never opened 07:08 No. 23 The lake that keeps its dead 08:02 No. 22 Pictures made for the sky 09:01 No. 21 The lake as big as a sea 09:55 No. 20 Lakes polluted on purpose 10:56 No. 19 The painter who vanished 12:03 No. 18 Silver found by a railway 12:54 No. 17 The gold rush that burned 13:51 No. 16 The reactor and the president 14:44 No. 15 Whales under the farmland 15:40 No. 14 The richest uranium on Earth 16:40 No. 13 Diamonds under the lakes 17:35 No. 12 Looking for diamonds, finding nickel 18:25 No. 11 Northern lights in stone 19:18 No. 10 The mountains that wore away 20:14 No. 9 A staircase for giants 21:12 No. 8 The hottest rock ever found 22:06 No. 7 The crystal eye 22:59 No. 6 The eye of Quebec 24:00 No. 5 The heart of a continent 24:52 No. 4 The city a comet built 26:00 No. 3 The oldest water on Earth 26:58 No. 2 The mountains of the spirits 27:51 No. 1 The oldest rock you can touch #CanadaHistory #Geology #Documentary #ExploreCanada #CanadianHistory #NatureDocumentary #Geography #TrueNorth Map imagery: Sentinel-2 cloudless 2016 by EOX IT Services GmbH (CC BY 4.0, contains modified Copernicus Sentinel data 2016).
