South Gully

About the easiest way to a nice summit with big view. One short sequence much harder than the rest which is mostly steep hiking, a little 3rd class scrambling.

About 620 vertical feet from parking to summit.

Could be useful as a descent route.

Approach: Trailhead with sign is on Old Mammoth Rd around GPS latitude longitude (N37.6186 W118.9932) -- not many parking spaces. After a short ways SE on the bike + hike trail, head off Left steep up SSE aiming toward Mammoth Rock. Higher up aim to the right of the rock, and reach the saddle connecting the rock with the main Sherwin Crest slope, around (N37.6144 W118.9915).

South gully starts a bit below the East side of the saddle ridge. Into the gully and scramble up its right side. Squirm under rock to get to left side of gully. Up a steep section with some thoughtful stemming moves (perhaps facing outward?). Next scramble up to reach the East ridge of Mammoth Rock. Hike roughly W up the ridge to the summit.

Around the "back" of the Mammoth Rock peak. A little down east from the saddle connecting Mammoth Rock to the main Sherwin Crest NE slope.

No hardware as of 2019.

Not many opportunities to place Trad protection gear.
