Access

Access this peak from ID-75. Turn west onto the Big Wood River access road, which leaves the highway 6.6 miles south of the ID-75/US-20 junction. This road will be difficult to drive when wet. Follow this occasionally maintained road as it heads west. You will come to a major junction signed for the Richfield Diversion to the left. Here, keep right and follow the road northwest until you are directly west of the summit. Keep your eyes peeled for a two-track on the north side of the road. You can either park at this point or follow the two-track about a hundred yards further to a parking spot. From here, you can make a gentle ascent to the peak’s summit ridge. The only obstacle you will encounter is a BLM fence you will have to cross or go under. See the map below.

West Face/South Ridge Route, Class 3

From the parking spot, climb up the west face while aiming for the ridge top to the right of the summit and left of the large grouping of pinnacles shown in the photo below. Once on the summit ridge, turn north and make the short climb up to the highest group of pinnacles.

The rocks comprising the peak’s highest point require a short stretch of class 3 climbing with some exposure. See the photo below for my route. Be warned that the exposure will bother some climbers. My route was 1-mile round trip and 347 feet of elevation gain.
