Intriguing little map based on the map and report of Peter Pond in 1787. The map traces the route from Lake Superior to Lake Winiping and then through an interconnected chain of lakes and rivers to Arabaska Lake and Slave Lake. The most interesting feature is the speculative river flowing out of Slave Lake, over "falls said to be the largest in the known world," and emptying into Cook Inlet.
