Jenney Stockade was a frontier outpost in the Black Hills of the Wyoming Territory. William P. Jenney, a former geology professor at the New York School of Mines, was commissioned by the U.S. Department of the Interior to build the stockade and establish the first white settlement in the area, near modern-day Newcastle, Wyoming. This was still Lakota Sioux land, as deeded by treaty. Jenney, and 432 soldiers under the command of Lt. Col. R. I. Dodge, would leave Cheyenne in June of 1875. There was a contingent of scientists, mapmakers, and a corps of mining engineers that made the journey.
Jenney Stockade would flourish from the start and become a stage station along the Cheyenne-Deadwood Trail. It would attract some famous visitors, celebrities of the day, like Wild Bill Hickock, Calamity Jane, and Wyatt Earp. Jenney Stockade is a National Historic Site, and much of the orginal cabin can be seen just outside the Anna Miller Museum in Newcastle.
