A large map drawn by Sergeant C. Becker and one of three maps resulting from Custer's Expedition. Drawn on a scale of 3 miles=1 inch. Topography is nicely developed with portions of Warren's route of 1857 and that of Raynold's in 1859 shown. This expedition led to a discovery of gold, a subsequent Gold Rush, and the tragic Custer Massacre.
