These remains are preserved as rare examples of the primitive chimneys built by the fur traders in their forts long before this region had a settled population. The Rocky Mountain House trading post was built in 1799 by North West Company. David Thomson wintered here in 1800-1, 1801-2, 1806-7, and from here he set out in 1807 for the discovery of the Columbia River. It was for over seventy years the most westerly and the most southerly post in the Blackfeet country and remained in operation until 1875.
