Northern Indian Canoe documented by Hearne
Couldn't help but think I had seen this paddle design before and after searching through my previous posts, I recognized the shape as one that Henry Schoolcraft documented in his journeys nearly a quarter-of-a-century later in a completely different area (1000s of miles away). This shape was described as a cedar paddle used by the fur trade companies. Might be an interested shape to copy - the straight sides would certainly make for quick and easy carving.

By the way, Mike, over at Reflections On The Outdoors Naturally wrote a recent post with all the relevant links to each episode of the Northern Wilderness series (my favourite is Episode 2). Many thanks for organizing these links!
