Woodruff Cabin Site is the location of the first European-American settlement in the Big Horn Basin of Wyoming.

John Dwight Woodruff built a cabin on Owl Creek in Hot Springs County in 1871.

Woodruff is believed to have built the cabin principally as a winter trapping camp and as a base for prospecting in the early summer.

[2] Woodruff sold the cabin to Captain R.A. Torrey of the U.S. Army garrison at Fort Washakie.

[1] The site is marked by a monument composed of boulders and petrified wood with a tile image and a bronze plaque, giving an erroneous date of 1873 for the establishment of the camp.
