LaHontan's illustration of a paddle
"The paddles they make use of are made from Maplewood, and their form is represented in the annex'd Cutt. The Blade of the Paddle is twenty inches long, six inches broad, and four Lines [1/3 inch] thick. The Handle [shaft] is about three Foot long, and as big [thick] as a Pigeons Egg"
What struck me however, is the chevron style decorative pattern on the blade which seems consistent with some of the earlier decorations posted in the Codex canadiensis and by Champlain.
