Bradford-Pearly House and Bradford House II

The historic Bradford-Perley House was built in 1860 and functioned as a station house for travelers along the Bradford Wagon Road that led to the mines near Fairplay, and later as a homestead to the Perley family. The nearby Bradford House II site has been a source of prehistoric artifacts more than 6000 years old. Ken-Caryl history experts will be on hand to explain the history and pre-history of these sites and the beautiful hogback area.
