Printed map. Cartographer unknown. Prime Meridian: London. "This exceedingly important map appeared in the March 1790 issue of 'Gentleman's Magazine,' a London publication of learned information. It is the only map detailing Pond's knowledge of this part of North America to be published in engraved form. Lines of latitude and longitude give it ballast, though who supplied them is anyone's guess."--Gough, Barry. The Illusive Mr. Pond: the soldier, fur trader and explorer who opened the northwest. Douglas & Mcintyre, 2014. Map donated by Dr. Karl Freeman, Hamilton, March 1995.
