Granite Mountain & Tusk O Granite

Named because of its location between Tuscohatchie Lake and Granite Mountain, Tusk O Granite is a small mountain just NW of the popular Granite Mountain on I-90. It can be easily climbed from Granite or make it its own adventure by climbing it from one of many trails around it. Loop trips are also possible.
Distance: 5+ miles
Summit Elevation: 5,566 feet
Elevation Gain: 4,200+ feet
Access Rating: Paved
The quickest access will be from trails at either exit 45 or exit 47 off Interstate 90.
Route from Granite Mountain:
From the summit, just scramble down the ridge to the saddle between the two peaks, class 2. The route up from the saddle is straightforward. You could also start a off trail climb from high on the Granite Mountain trail before it crosses the avalanche paths. There is a bit of brush at first but the terrain opens once you reach the bowl south of the peak.

Fire Lookout History
One of the earliest lookouts, a 1916 mountaineers journal describes the summit as having a summer forest lookout station there. The Oregonian newspaper made mention of the lookout on August 17, 1917. The summit for sure had a cabin in a 1920 photo. In 1924 an elevated D-6 cupola cabin was constructed. "The material for the new lookout house was cut from regular mill stock by the carpenter prior to packing it to the lookout site. In order to correct a problem of snow blowing into the house, a new product from Weyerhaeuser, Balsam Wool, was used as additional insulation. The shutters were hinged from the top of the window frames, when open, they were propped up by rods creating a sun shade." (Six Twenty-Six) Around 1956, the present 10 foot treated timber L-4 tower was built. Granite Mountain was used during WWII by the Aircraft Warning Service, there are some documents below explaining more about this.
