Ascent Trip Report

The original trail from the standard TH near Diamond Lake to the PCT was closed in 2007(?) due to an impressive blow-down that took out many hundreds of trees. A trail crew was rebuilding the original trail as of July, 2013. After crossing the PCT, follow the obvious climbers trail southeast. Higher up, the trail has many threads. If in doubt, stay left lower down and stay right higher up. As you swing around the right side of the peak, a short but easy 3rd/4th chute leads to comfortable ledges below the summit pinnacle. Descriptions of the final 80 feet range from 3rd Class to 5.2. Unless I missed an easier route, the summit pinnacle is NOT 3rd Class. We stayed toward the right side of the east face and found the difficulty to be solid 4th Class. Going up is not a problem, but those not comfortable on 4th Class would probably find the downclimb to be frightening. We took a 90' rope which was just long enough to belay the summit pitch and single-line rappel back down. The summit pitch is on good quality rock and helps make for one of the best alpine peaks in Oregon.
