The unusual landforms of Writing-on-Stone / Áísínai’pi resulted from the dynamic interaction of geology, climate and time. The sedimentary rocks exposed in the Milk River valley were formed 85 million years ago at the edge of a great inland sea. Huge volumes of meltwater began eroding the soft sandstone after the last ice age. This is how the coulees and hoodoos you see today were formed. The unique habitat created is suitable to many diverse species not typically found in surrounding areas.
In Blackfoot traditions, the world around us is the work of Náápi who gained his powers from the Creator. Náápi did a wonderful job making the land. Special places like Writing-on-Stone / Áísínai’pi are here for a reason. This is where significant things happened to the ancestors of the Blackfoot. This is where the ancient stories took place.
