Hi Andy,
I used to own that canoe. It is a 1979 Chestnut Prospector, one of the last built before the factory closed. The photo was taken at our campsite on St. Regis Pond, in St. Regis Canoe Area of the Adirondacks right before WCHA Assembly.
It's a great canoe, it now makes its home in Quebec.
Cheers,
Dan
