Peak 9584 is the highest point on the north side of Rock Creek Basin in the Eastern Centennials. It is overshadowed by its neighbor to the southwest, mighty Mount Jefferson (10,203 feet). Peak 9584 sits above Lake Marie and is most easily climbed via its southwest ridge and the Rock Creek Basin Trail. USGS Sawtell Peak
Same as for Peak 9500. This is the final leg of a 2-peak journey that begins at the Sawtell Peak trailhead.
Southwest Ridge, Class 1
From the 9,020-foot saddle at the base of the southwest ridge of Peak 9500 (and at the head of a prominent gully that leads down into Rock Creek Basin), follow FST-165/Rock Creek Basin Trail northward down into Rock Creek Basin. The trail turns left/northwest to climb over 200 vertical feet and cross the headwaters of Rock Creek then descend right/northeast to a saddle at the base of the southwest ridge of Peak 9584. This saddle is at 8,940 feet.
The Climb, Class 2
From the 8,940-foot saddle at the base of the southwest ridge, scramble north up a face of easy scrub/brush, crossing multiple berms and terraces (from phosphate mining operations of years past) to reach the [easier] southwest ridge. Please note that heading northwest from the saddle to immediately reach the southwest ridge is not a good idea due to cliff bands and rocky outcrops/towers near the base of the ridge. Once on the southwest ridge, follow it on short scrub and scree/broken rock to the summit. The summit of Peak 9584 has a tall summit cairn and magnificent views of Henrys Lake, Red Rock Pass, and Mount Jefferson.
