DRIVING

From Bishop drive north out of town on hwy No 6, exiting left at Five Bridges road after 1.5 miles. This only road crosses the river, bridge still under construction, and then swings west past a gravel facility to a 4 way intersection. Left on Chalk Bluff road is to the Happy Boulders, right is to Fish Slough, a good spot for birds, and straight is the Casa Diablo road. This was excellent to dirt all the way. Drive 15 miles to a signed intersection directing through traffic left and out to the Benton Crossing road. Turn right 0.6 miles of still good dirt and parked before the road deteriorates markedly. Park here. At this point you are 0.6 miles NNE of the mountain.

HIKING

Easy walking up through the pinyon forest brings you to the rocky ridgeline. Climb past two false summits and over to the true one which is the furthest south. Surprisingly intricate third class leads up the final 200 feet.

NOTES

This is the peak south of Glass Mtn and visible to its right from Bishop, a proper WIMP ( Winter, Inyo, Mono, Peak ).
