Martha Canary, 1852-1903, "Calamity Jane" full-length portrait, seated with rifle as General Crook's scout
Calamity Jane was often around Fort Laramie. For a time she worked at Three Mile Ranch (a house of ill repute) near Fort Laramie Military Reservation. She often dressed as a man to work with the army. This way she joined Professor Jenny's Expedition in 1875 disguising herself as one of the cavalry troopers escorting the expedition.
