The land and monument for this site were donated by the Great Northern Railway to honor explorer and geographer David Thompson, who passed this spot in 1797 and 1798 while on a scientific and trading expedition for the Northwest Company, a Hudson’s Bay Company competitor. Thompson made the first reliable map of the region between what is now North Dakota and Lake Superior. His early knowledge of the people and landscapes was so precisely reliable that Lewis and Clark reportedly used a Thompson map on their 1804–1806 expedition. The monument consists of a granite globe on a rectangular granite base.
