Elevation: 8,460 ft
This peak is not in the book.
Diamond Rock is a misnamed peak since it is not capped by an impressive rock. Nevertheless, it is a worthy goal for peakbaggers. It sits above beautiful Summit Lake at the northeast end of Diamond Ridge. Diamond Ridge is located northeast of Upper Payette Lake on the East Side of [paved] Warren Wagon Road which leaves McCall on the West Side of Payette Lake. The best access currently is to follow Warren Wagon Road north for 21.1 miles and then turn right/east onto FS-431 and follow this decent dirt road to its end.
You can hike cross-country to Summit Lake and then up to the summit from the trailhead. Be forewarned that this area was heavily burned and, in places, cross-country travel requires crossing acres of downed trees. I climbed this peak from Diamond Ridge Peak as part of a traverse of the ridge with John Platt in 2015. For additional details, see my Diamond Ridge Traverse page and John’s trip report where you will find a GPS track showing our route. USGS Victor Peak
