South Ridge Route, Class 2 by Livingston Douglas 

From the 9,100-foot saddle south of the peak, scramble NW then N up the ridge to the summit. This is a tedious endeavor on somewhat unstable shale. It takes almost 30 minutes to cover the 1/2 mile of distance involved. You’ll pass one ID/MT Boundary Post en route and find another one on the summit.

To return to the Fourth of July Creek Road area, descend SW then S from the 9,100-foot ridge saddle into a rather flat but convoluted basin that has undulations, forest, boulders, vegetation, and marshy areas. Drop to 8,300 feet and contour S then SW to intersect the CDT. Follow the CDT back to the ATV road then follow the ATV road back to FSR-256 and the parking area near the large mud hole in the road.
