In the sixteenth and seventeenth centuries, large vessels were fashioned from cedar, poplar and cottonwood trunks. But how big, how numerous and how widely dispersed were these canoes? How far back do they go in time, and how did the introduction of European metal tools influence or alter the construction of these boats? The May 3 talk will suggest preliminary answers to these and related questions. The event is co-sponsored by the Indian Peaks Chapter of the Colorado Archaeological Society.
