One of the most interesting sights in southern Alberta, and a World Heritage Site, is the curiously named Head-Smashed-In Buffalo Jump. This excellent interpretive center/museum is built into the edge of a steep cliff over which the First Nations peoples used to stampede herds of bison, the carcasses then providing them with meat, hides, and horns. The multimillion-dollar facility tells the story of these ancient harvests by means of films and Native Canadian guide-lecturers. Other displays illustrate and explain the traditional life of the prairie-dwelling natives in precontact times and the ecology and natural history of the northern Great Plains. Hiking trails lead to undeveloped jump sites.
