Bradford House II is a prehistoric rock shelter in Jefferson County's Ken-Caryl Valley, southwest of Denver, where naturally protected sandstone formations offered cover, tool stone, and access to varied plant and animal resources. Its mild semiarid setting and south-facing position made it especially useful in winter. Excavations in 1973 uncovered cultural features, thousands of chipped stone artifacts, ground stone tools, ceramics, bone tools, and animal remains, showing repeated use over about 4,500 years during the Middle and Late Archaic and the Early and Middle Woodland periods. Finds point to food gathering, hunting centered on mule deer, and everyday domestic work within a resource-rich foothill corridor.
