The aboriginals of the Fraser Canyon once used pit houses as a form of lodging primarily important in the winter, a warm safe haven during the cold winter months. A pit house is North America’s oldest known permanent housing. The Pit House is built by digging a circular or oval crater in the ground several feet deep, then a log structure is built over top with a wooden roof sealed in with various resources used from the surrounding nature. The entire structure is then buried with only an access door at the top and on the side at the bottom. The access door on the top is used by men and the door on the side is for women, children and elders to enter.
