I spent much of 1977 living in an informal community on 200 beautiful acres on the valley of the North Saskatchewan River in Alberta. This small tipi was my home during the summer months. Actually, because of the mosquitoes I slept in an adjacent pup-tent. There was also a plague of forest tent caterpillars that year; they used to drop from the aspen trees like rain, and you had to put a saucer over your cup to keep them out of the coffee. The chickens sure loved 'em, though.
The poles are jack pine or lodgepole pine, obtained from a nearby muskeg.
