"The dugout canoe, which was likely made from a tree that once grew in Wisconsin, is one of more than five dozen located, catalogued, and photographed by [Sissel] Schroeder and [Tamara] Thomsen as part of the Wisconsin Dugout Canoe Survey Project, an effort to identify and document the origin, style, and tree species used to make dugouts. The team is also building a library of 3D interactive digital models of the dugouts, which is available to the public online."
