Description
This monstrous block of Rocky Mountain quartzite is known as a 'glacial erratic', but locally it is known as 'Big Rock'. Big Rock weighs 16,500 tonnes and measures at about 41 x 18 x 9 meters and the erratic is one of the largest glacial erratics in North America. "Big Rock†was deposited during the retreat of the Cordilleran ice sheet at the end of the Late Pleistocene to early Holocene periods. The massive quartzite rock came from an area close to Mount Edith Cavell, in Jasper National Park. Alberta prairies (near okotoks)
