Arthur Peak (winter)

Arthur Peak is a winter scramble near the Carbon River in Mount Rainier National Park, with 3,470 feet of elevation gain. Most of the trip is in mossy old-growth forest, in avalanche-safe terrain.

ASCENT ROUTE

Start at the Carbon River entrance gateHike the abandoned road for about 2 mi to the trail toward Green Lake. Follow this, leaving trail at 3,200 ft. Head  west, picking up the lower slope of Rust Ridge. Climb heavily timbered hillside looking for a steep loose gully to attain the ridge. Make sure you mark spot where you came up for descent. Run the ridge south to the summit, no difficulties.

It is also possible to ascend the northwest ridge of Arthur directly from the road but this interesting variation requires good route finding skills and includes lots of brush and logs.
