"During the summer of 1846, the 87 members of the Donner Party travelled an untested route between Fort Bridger, Wyoming, and the Humboldt River, Nevada. As a result of delays caused by this choice, they became stranded by heavy snows on the east flank of the Sierra Nevada. By the time the last member of the party was rescued, 40 had died" [Donald K. Grayson, 1990].
