This wooden tower, approximately 63 feet high, is standard but its cab is unique. It looks like an R-6 flattop design, but it is not. The cab was designed by the Forest Products Lab in 1963 at the request of the USFS Region 6 engineers. They were looking for lightweight materials, including new wood products recently available but not yet used for lookout cab construction. Besides being lighter weight, the cab was to be prefabricated off site, then packed in bundles that could be delivered on site by helicopter. This a procedure similar to how the L-4 cabs of the 1930s were packaged to be delivered by mule train. Being a trial design, they elected to construct it at a location accessible by road.

For whatever reason, cost or maintenance, this design has not been used again.
