Mt. Bonaparte on the Okanogan National Forest in north central Washington may have been used as early as 1906 as a tent camp lookout. The first 12' x 12' flat-hewn tapered wall groundhouse with tower was constructed in 1914 and the house portion remains today as a storage building. The present 15' x 15' R-6 flattop cab and catwalk on a 20' timber tower was built in 1963 and remains in active service.
