This detailed map was reduced from six sheets to one and covers eastern Wyoming, western Nebraska and South Dakota, and southeastern Montana just past the Tongue River. It shows Captain William Stanton's fourteen different reconnaissances from 1875-77 which included stops at Deadwood, Hat Creek, Fort McKinney, Custer City, Camp Robinson and many more. Wheat notes that the Montana portion of the map includes dates from June 1876, reflecting Crook's operation against the Sioux. Drawn by R.E. Koehnemann, Draughtsman and Topographer.
