Rhoades Valley Fort was erected in 1866-67 for protection against hostile Indians. It was 30 rods square, with walls 16 feet high built of logs that formed the back walls of the houses, and with gates in the east and west walls. About 47 families lived in the fort from the time of its erection until it was abandoned about 1870. The town of Kamas (Rhoades Valley) was surveyed and divided into lots in 1869-70.
