FIRST EDITION of Simpson's work describing his winter journey from the Red River to Athabasca from 1836-1837, and his return trip during the winter of 1839-1840. "During the trip the expedition encountered many western Eskimo and traded with them. Simpson's description of these natives and of the geological features along the route is valuable for the history of the early exploration of this region of Alaska" (Lada-Mocarski).
