Porphyry Peak is the westernmost 10,000-foot peak in the White Knob Mountain Range of the Challis National Forest, in Custer County. Porphyry has a uniquely colored and shaped summit block that makes it easy to locate from Copper Basin Road. From the peak’s summit are spectacular views the surrounding country including beautiful Copper Basin and peaks in the Lost River, Pioneer, and White Cloud mountain ranges.
2016 Trip Comments
Steve and Margo Mandella provided additional photos and a track from their 2016 ascent.
Margo reported: We caught this peak on a beautiful day, Tom. No, it wasn’t sunny and it was very cold when we started out, but the air was perfectly still and the silence was deafening (except when we were by the river). We felt that we had the entire place to ourselves and didn’t see a soul all day.
We followed your Idaho – A Climbing Guide route, accessing the south ridge from Castle Creek Canyon. You have good views of the peak throughout the ascent, so route finding is not an issue. The steepest part of the climb is just the short summit block. We would have tagged an additional peak, but weather was coming in that day (it started raining when we arrived back at the car). We climbed the peak in October when we thought the river would be at its lowest before winter set in. That strategy worked really well for us. Crossing in sandals helped too.
