 Similar structures are used in the sweat lodges that are common in First Nations communities today, though those are made out of sticks instead of logs, with branches and blankets instead of earth as a covering.As with sweat lodges, some quiggly holes were once undoubtedly used for ritual and community as well.Although found to a limited degree on the southern British Columbia Coast and Puget Sound where log-frame longhouses and lean-to structures are more common, they are the main trait of native pre-Contact archaeology throughout the Interior cultures, and may have variously been either seasonal or permanent settlements.
