Walk up Forest Road 170 from the junction with Forest Road 4304. The track climbs into a clearing where you can turn and see glorious views to the south and west.
At about 0.5 mile you’ll reach a gate. The barbed wire fence on either side is down, so you can carefully step over it and proceed another 0.1 mile to the top of the butte.
There you’ll find the cap of the lookout tower on the ground, along with stacked lumber and hardware from the legs, and some outbuildings… including a white-painted outhouse tucked discreetly amongst the trees.
Tall evergreens obstruct any distant views from the ground, but spring wildflowers, autumn color, and wildlife surround you. Return to the trailhead via the same route.
This trail would make a nice snowshoe or ski ramble if you have a vehicle that can get you there, but note that this is a dry trail and there is no camping allowed.
