This route provides access to Mt. Marvine during summer months without access to a 4 wheel drive vehicle to access UM Pass. Round trip is roughly over 3 miles, with 2335 feet of elevation gain.

Getting There

Approach the Fish Lake area via Loa from Highway 24 or I-70. If approaching from I-70, leave the freeway between mile post 84 and exit 89, and go southwest on State Road 72.

Once in the Fish Lake area, drive north to Johnson Valley Reservoir, and at the lakes northwest corner, drive north on the Sevenmile Creek dirt road. Drive just under three miles to the Ross Retreat Cabin area, located on the east side of the road. Park along the dirt road.

Route Description

Once parked, the hike starts out at roughly 9,275 feet. This entire route requires route finding as there is no trail. Walk east along the fence, and continue up through the pines and aspens, you may pass a cattle pond or two. Keep a general orientation for the ridgeline to the east, south of the summit. Towards the upper portion of the ridge, some boulder hopping is required in certain areas as the basalt rock ranges from the size of your fist to a small car. Just under the ridge area it does get somewhat steep, but not dangerous.

Once on the ridge proceed north to the summit over mostly class 2 terrain, class 3 in only a couple small sections. The descent is the same route down, be careful to not be off route to the south as the forested area is fairly dense and can make progress difficult.

Essential Gear

General day hike items, more rugged boots or shoes for boulders and talus on the upper portion of the climb.
