Parker Pass
Peak · 11,102 ft · Yosemite corridor
Parker Pass is an 11,102-foot peak in the Yosemite corridor of California's Sierra Nevada, sitting at the junction of high-alpine exposure and the eastern Sierra escarpment. The pass is typically windier and colder than lower Yosemite Valley elevations.
Parker Pass faces sustained wind funneling off the Sierra crest, with afternoon gusts common. Morning calm periods last 2 to 3 hours before flow accelerates. Snow cover persists through spring; wind scour creates variable terrain. Visibility can drop rapidly when storms push west.
Over the past 30 days, Parker Pass has averaged 13 mph wind and 18 degrees Fahrenheit, with gusts reaching 40 mph and a NoGo Score averaging 34. The week ahead continues that pattern of morning windows and afternoon deterioration. Plan for high-altitude exposure and avalanche-prone slopes until late spring snowpack stabilizes.

About Parker Pass
Parker Pass sits at 11,102 feet on the Yosemite corridor's eastern rim, straddling the crest between the Sierra Nevada's main divide and the Mono Basin drainages. Access from the west runs via Highway 120 through Yosemite National Park; the Tioga Pass gateway sits roughly 30 miles east. The pass is a natural climbing objective and a transit point for backpackers crossing the high Sierra. Its position on the rain shadow side of the crest means it receives less precipitation than western slopes but holds snow later due to altitude and wind-sheltered gullies.
Winter and spring weather at Parker Pass is dominated by funneled wind from the northeast; the 30-day average wind speed is 13 mph with gusts to 40 mph, sustained by the pressure gradient between the cold Mono Basin and the Pacific systems. The 30-day average temperature is 18 degrees Fahrenheit. Avalanche terrain is significant; the pass feeds into steep snow-loaded slopes on both flanks. Conditions are most stable in late summer and early fall, when snowpack has consolidated or melted and wind patterns relax slightly. Summer climbing sees reduced crowding (an average of 3.0 on the rolling 30-day scale) compared to highway approach corridors. Highway 120 opens irregularly based on snowpack; early-season attempts coincide with high avalanche hazard and unstable wet slabs.
Parker Pass suits climbers with winter mountaineering experience and backpackers crossing the high Sierra during stable snow seasons or summer. Approach from the Yosemite side requires navigation of high-elevation meadows, talus, and potential snow fields. Afternoon wind makes summit attempts a morning-only proposition; plan to start before dawn and descend by early afternoon. Parking at the Tioga Pass entrance or Tuolumne Meadows area fills on weekends; arrive by 7 a.m. or expect to turn back. Avalanche hazard demands current conditions knowledge; check the Sierra Avalanche Center forecast before any spring or early-summer attempt.
Nearby climbing objectives include Mount Dana (13,053 feet) and Mount Gibbs, both accessible from the same Highway 120 corridor and sharing similar wind exposure and avalanche terrain. The Yosemite high country to the west offers gentler approach routes but longer logistical commitments. Mount Whitney, on the southern Sierra, sits in a drier rain shadow and has lower average wind speeds but sees 10 times the crowding. Parker Pass rewards solo ascents or small parties with patient planning and early starts.
