August 20, 1963: "Construction of a new Deschutes National Forest lookout, in the Green Ridge country, has been completed and is now manned, with Sig Skavlan, Jr., Bend, on duty. The new lookout is unique in that it is not located on a high peak to provide a 360 degree sweep of the Central Oregon horizon, but faces in only one direction, west. Visible are the timbered areas in deep canyons of the eastern Cascades, where considerable slashing from timber cutting remains on the ground. It is an area of high fire hazard. The lookout was constructed with brush disposal funds. A Portland prefabricating firm was in charge. Built on a westward facing rocky ledge, the new lookout is a cabin-like structure, not a viewpoint on high stilts. From the building, the lookout can obtain an 180 degree sweep of the east slopes of the Cascades, from canyons leading up to Mt. Jefferson south to Jack Creek and other timbered draws east of Mt. Washington." (The Bend Bulletin)
