Peak 6643 is a rugged, rocky outcrop amongst a sea of sagebrush hills that separate Jeffs Creek from Mill Creek in the Eastern Salmon River Mountains. It is a short climb from Jeffs Flats Road/FSR-079. USGS Pats Creek
North Ridge, Class 3
From the base of the lowest gully that separates Peak 6260 from Peak 6643, scramble up a prominent gully on the northwest side of Peak 6643. The gully climb is through easy, gapped sagebrush and leads southeast up onto the north ridge at a saddle (6,220 feet). Follow the ridge southwest then south up steep-ish scrub and embedded boulders/talus with some rocky ridge outcrops along the way. Cross to the left/east side of the ridge higher up then climb back up onto the rocky, very steep ridge crest (Class 3). Continue climbing up the ridge, cross over a rocky ridge point, and drop 25 vertical feet to a minor notch. From there scramble south up to the small, rocky summit perch. The summit has a small cairn atop the highest boulder.
East Ridge/East Face, Class 3
From the summit, descend the rocky east ridge (then east face) to a 2-track road. The east ridge requires a Class 3 downclimb of a headwall high up. After descending a section of steep talus/scree, you will be relieved to reach the gentler sagebrush slopes below. Bushwhack through the sagebrush to reach the 2-track road at a junction in a saddle. Follow the 2-track road left/north until it intersects Jeffs Flats Road. Go right/east onto Jeffs Flats Road and follow it back to its junction with Mill Creek Road and your parked vehicle.
