The Haddenham Cabin is located in the southeast portion of Fossil Butte National Monument, 10 miles west of Kemmerer, Wyoming. It is located on the Quarry Trail, which is a 2.5-mile loop leading to the south face of Fossil Butte. The cabin has local significance for its association with the quarrying of fossils in the Green River Formation. The cabin was built by David C. Haddenham ca. 1918 to serve as on-site shelter for himself and his family during their seasonal quarrying work. He actively quarried in the area of the present monument from the late nineteenth century to his death in 1968. From this work he provided universities, museums, and private collectors with specimens of rare fossils dating back 40 million years. The period of significance dates from 1918 to 1950. The cabin was used after the historic era into the 1960s.
