Mount Fernow/Southwest Slope

The highest peak in the Entiat Mountains, Mount Fernow offers a challenging, strenuous scramble. Your routefinding skills will be tested in the 22 miles and nearly 6,000 feet of elevation gain.

getting there

Drive SR-2 east to Coles Corner.  Head north on SR-207 toward Lake Wenatchee, turning right at the southeast end of the lake.  Turn left onto Chiwawa River Road (Forest Road 62) and follow it over 25 miles, passing the Alpine Meadow Campground.  Look for Phelps Creek road branching on the right and follow it about 2.5 miles to the Phelps Creek trailhead (4,100).

APPROACH

Hike Phelps Creek trail about 3.5 miles to Leroy Creek.  After crossing the creek look for a trail headed up to the right. Follow this steep, dusty trail 1.9 miles up to Leroy Basin with good camping (6,100 ft).

ASCENT ROUTE

From Leroy Basin camp, head north to a slight saddle in the ridge.  This is a cross-country route that ascends heather and scree. Cross the saddle and drop ~100 feet then traverse north up ~400 feet to a small lake (a possible bivy campsite alternative). Continue north up ~200 feet and across another slight saddle. Descend ~700 feet, traversing Gloomy Glacier (what remains of it), and climb the slope on the northeast side to another basin. Then ascend slopes which start as a steep gully then become gentler with possible snow patches to a saddle in the ridge south of the summit.  Head north towards the summit skirting obstacles to climb on reasonable terrain.

DESCENT ROUTE

Descend the climbing route.
