Tepee

This low cost summer home, a tepee, appears to be cool and spacious. It was erected quickly from natural materials. The frame is long, slender saplings. The skin is tree bark. The bark is held in place by lashing additional saplings to the framework. The door is very large. . . allowing good air circulation. The structure is waterproof and much of it is portable.
To me, this American Indian home was as high-tech in the seventeenth century as the Birch bark canoe. This tepee stands at St Ignace in the upper peninsula of Michigan.
