Peak 6601 is a rugged outcrop that sits above the convergence of Basin Creek and Hayden Creek in the foothills of the Lemhi Range. It is most easily climbed from Basin Creek Road and its southwest shoulder. The east and south aspects of Peak 6601 are particularly rocky and rugged. USGS Hayden Creek

From the small hamlet of Lemhi along ID-28 about 18 miles north of Leadore, drive northwest on [signed] Lemhi Road for 0.8 miles to a signed “T” junction with Hayden Creek Road. Turn left/southwest onto paved Hayden Creek Road and follow it for 2.7 miles to a [signed] junction with Basin Creek Road. Go right/west onto Basin Creek Road and drive 0.3 miles to a large pullout on the left/south side of the road. Park here (5,525 feet; 44⁰50’10”N, 113⁰40’44”W). Please note that if you access Hayden Creek Road from its signed junction north of Lemhi, it is 3.3 miles southwest to the road junction with Basin Creek Road.

South Face/South Shoulder, Class 2

The Climb

From the large roadside pullout, cross to the north side of Basin Creek Road and scramble north up a VERY STEEP grass-and-sagebrush slope (with some embedded, sloped slab rock) to intersect a shoulder that is dotted with mountain mahogany. Go right/northeast onto this shoulder and climb it in semi-open terrain in reasonable scrub. This shoulder leads up to the southwest side of the summit cap. Continue northeast then east to the small summit, weaving through a thicker forest of mountain mahogany high up. The semi-open summit had a torn-down cairn which I rebuilt.

West Ridge/Southwest Shoulder, Class 2

The Descent

From the summit, descend west on the rounded ridge, weaving through the mountain mahogany. Emerge from the mountain mahogany and downclimb some easy cliff bands to reach a magnificent open shoulder of easy field grass. Descend this shoulder southwest to near Basin Creek Road. Find a cattle trail to drop off a rocky buttress and reach the road about 0.2-0.3 miles west of the roadside pullout from which this climb began. The descent route is in much easier, flatter terrain than the ascent route.
