Access
From US-93 at the north end of Challis, turn left/west onto [signed] Clinic Avenue. Follow Clinic Avenue as it goes west briefly, then jogs north briefly, then heads west to a “T” junction with [unsigned] Challis Creek Road. This junction is 0.4 miles from US-93. Turn right/north onto Challis Creek Road and drive 7.1 miles to a sharp bend in the road that goes around the base of the steep toe of the southwest ridge. Drive another 0.1 miles to cross Eddy Creek and reach a parking area on the right side of the road at an unsigned junction. Park here (5,470 feet).
Southwest Ridge, Class 2
The Climb
From the unsigned junction, hike east on Challis Creek Road back to the toe of the southwest ridge of Peak 6660. Continue east on Challis Creek Road for about 50 yards to reach a sagebrush slope that is steep, but climbable. Leave the road and scramble north up onto the crest of the southwest ridge. Once on the ridge, follow it northeast then left-ish/north to skirt the left/north side of a steep scree/gravel slope.
Return right-ish/northeast back onto the ridge crest after bashing through sagebrush with some areas of loose scree/gravel underneath. There is a final patch of talus/scree to climb in order to regain the ridge crest. Once back on the ridge crest, scramble northeast then north to reach a flattish area at 6,580 feet. Angle right-ish/northeast in sagebrush to cross the head of a dry gully at a saddle. From the saddle, continue east up to the gentle, sagebrush-and-gravel summit of Peak 6660.
