Shout-of-Relief Pass
Peak · 11,427 ft · Mammoth Lakes corridor
Shout-of-Relief Pass sits at 11,427 feet in the Mammoth Lakes corridor of California's Sierra Nevada. A high alpine saddle with avalanche terrain, it rewards calm mornings and punishes afternoon wind.
Wind funnels through the pass by mid-afternoon, driven by thermal circulation off the eastern Sierra basin. Morning windows are narrow but manageable. Snowpack instability is a primary concern during spring consolidation cycles.
Over the last 30 days, the average wind speed has held at 15 mph with gusts to 43 mph; conditions score averaged 36. Expect similar patterns ahead: morning lulls before 10 am, then sustained wind build into evening. Temperature remains in the low 20s Fahrenheit; avalanche terrain requires current advisory consultation before any approach.

About Shout-of-Relief Pass
Shout-of-Relief Pass is a high alpine saddle in the Mammoth Lakes corridor, sitting between peaks on the eastern Sierra crest. Access is by foot from the Mammoth Lakes basin via established routes, with approach time of several hours from trailheads on the west side of the range. Highway 395 runs the eastern base of the Sierra; Highway 203 connects Mammoth Lakes town to the main corridor. The pass lies within terrain mapped for avalanche hazard by the Eastern Sierra Avalanche Center (ESAC). At 11,427 feet, it is substantially higher and more exposed than the valley floors of Mammoth Lakes proper.
Conditions at Shout-of-Relief Pass are dominated by afternoon wind. The 30-day average wind speed is 15 mph, with recorded gusts to 43 mph. Morning hours, typically before 10 am, offer the calmest window for travel. By midday, thermal wind builds steadily as solar heating drives air up the eastern slope and through the saddle. Temperature averages 23 degrees Fahrenheit in the rolling 30-day window; highs rarely exceed the mid-30s even in summer. Spring brings avalanche hazard as snowpack consolidates; ESAC advisories are mandatory reading. Crowding remains minimal at 2.0 average visitors per day, reflecting the route's difficulty and high-altitude commitment.
Shout-of-Relief Pass suits mountaineers, ski mountaineers, and experienced alpine hikers comfortable navigating terrain above 11,000 feet in variable snow and wind. Plan to depart the trailhead before dawn to reach the pass in the morning wind window and descend before afternoon gusts peak. Carry an avalanche beacon, probe, and shovel; check ESAC advisories for recent slab activity on approach slopes. Do not attempt the pass in whiteout or during advisory-level red or considerable instability ratings. Winter and spring ascents demand crampon technique and crevasse awareness.
Nearby alternatives in the Mammoth corridor include lower-elevation saddles and passes with less avalanche exposure but comparable wind patterns. Comparison passes like Mono Pass or Parker Pass offer similar high Sierra conditions at marginally lower elevation. The corridor as a whole sits in the rain shadow of the Sierra crest; storm tracking is more about systems crossing the Great Basin than Pacific moisture. Cumulative 365-day data shows temperature swings from a low of 10 degrees Fahrenheit to a high of 36 degrees, and sustained gusts to 43 mph.
