Okotoks Big Rock, the largest glacial erratic carried in glacier ice from Mount Edith Cavell, Rocky Mountains to the prairies during the Pleistocene
Okotoks Rock is part of the Foothills Erratics Train, quartzite rocks that were part of Mount Edith Cavell in the Rocky Mountains. The rocks were carried by glacier ice during the colder climate of the Pleistocene Ice Age and deposited in a swath across the North American prairies from Jasper National Park to Montana. This rock, the largest of the erratics in the train, was carried almost 400 km and deposited west of the present-day town of Okotoks about 10,000 - 12,000 years ago. The Indigenous name for the erratic is derived from the Blackfoot people's word for rock "okatok." The Okotoks erratic has been designated as an Alberta Provincial Historic Resource.
