Big Rock (Okotoks Erratic)
Okotoks Erratic
A boulder of roughly 16,000 tonnes carried by glaciers from the Jasper area, standing alone on the prairie. It is a sacred stone in Blackfoot legend.
This quartzite boulder is about 41 metres long and 9 metres high, and has split into two halves. Glaciers carried it during the Ice Age from the Jasper area, hundreds of kilometres away, and it is the largest of the boulders along the Foothills Erratics Train. In Blackfoot legend, the trickster deity Napi angered the boulder, which then chased him until a bat smashed it and saved him. There are a trail and interpretive signs on site, but please do not climb. It is about a 40-minute drive south of Calgary and free.
