Summit:
W7O/SE-032
Dry Mountain is a drive up summit near the Burns-Hines area with a lookout tower and cabin. To get there I recommend this route:
Turn north off of US-20 at 43.5467, -119.0847 onto NF-47, aka Hines Logging Road.
At 43.64275, -119.2629 turn west onto US-41, aka Donelly Road.
At 43.7038, -119.3953 turn onto US-4120, aka Beaver Slide Road.
Stay on this road until you find a lookout tower.
The road is very good to good until the last half mile or so where it gets a bit rough. Possibly not Priusable, but easy in a Rav4 or higher clearance vehicle.
