A view looking west at Potosi Mountain. The east side has a band of cliffs, but we found a route up. The highest point is right next to the furthest north radio tower.  Photo by Shelley Rogers, March 21, 2016.
The upper route through the cliffs as seen from the saddle just west of peak 7551 ft. From points P25 to P27 you want to stay close to the cliffs. Near point P28 you can find a way up through fallen trees and some easy rock to the summit. You will come up right to a cable tray below the northern tower. Move right to the top along the cables.

Driving Directions: From exit 12 on Interstate 15 take Nevada 161 north to Goodsprings. Just before the town go right on the paved truck bypass. After a mile or two go right at stop sign onto a fair dirt road heading north to Cottonwood Pass. Follow this road for about 6.8 miles to a signed road 800C on your left. This road gets really bad with a lot of rock and high-clearance four-wheel drive is needed. For some of the route take a newer parallel road on the left that is much less rocky. We parked across a short dip at point P1.

Hiking Directions: Follow the old road past the mine area and go right across a small canyon passing a concrete tank at P3. Stay on the road as it turns into a sandy wash. At P6 continue in the narrow wash to P8 where you will intersect an ATV track. Follow this up to a minor saddle at P11. Drop down some and cross brushy slopes and eventually go into a route in the canyon bottom at P16. The canyon appears to have been cleared as a trail a long time ago. The canyon fades out so head up brushy slopes to a saddle at P20. From here head up to the cliffs, staying close to them until P27 where there is a canyon going up to the summit. This route is 7.4 miles round-trip with a gain of about 3300 ft. It took us about 4 hours to reach the top and 2 1/2 hours down.  There is an ammo box register at the top. We could not find benchmark disk Olcott. There is a USGS datasheet: FS1016   3/16  RLC
