Haeckel-Wallace Col
Peak · 13,032 ft · Kings Canyon & Sequoia corridor
Haeckel-Wallace Col sits at 13,032 ft in the Kings Canyon and Sequoia corridor, a high Sierra pass connecting remote alpine basins. Wind and avalanche terrain define the approach.
Wind averages 11 mph but funnels hard through the col itself, especially afternoons. Temperature stays in the low 20s F even in late spring. Snow persists into early summer. Morning calm precedes afternoon gusts; afternoon crossings mean exposure to wind-slab hazard on steep approach slopes.
Over the last 30 days, Haeckel-Wallace Col averaged a NoGo Score of 37.0 with wind at 11 mph and temperatures around 19 F. Crowding remains minimal (2.0 average), typical for a high-alpine pass that sees traffic only during brief summer windows. The week ahead will follow this pattern: expect marginal stability, rising winds by day's end, and continued low traffic.

About Haeckel-Wallace Col
Haeckel-Wallace Col is a high Sierra pass in the Kings Canyon and Sequoia corridor, straddling terrain between the Evolution Basin to the west and Inyo National Forest drainages to the east. Access requires backcountry travel; there is no direct highway approach. Trailheads on Highway 395 near Big Pine or via Highway 168 and the Kearsarge Pass Road serve as primary gateways, with drive times of 2 to 3 hours from Bishop or Independence. The col itself sees traffic only from experienced backpackers and mountaineers undertaking multi-day Sierra crossings.
Conditions at the col are shaped by elevation and aspect. The 30-day average temperature is 19 F, with a year-round range from 8 F to 33 F. Wind averages 11 mph over the rolling 30 days but gusts reach 38 mph, concentrating in afternoons and on weather-system fronts. Snowpack typically governs the season: the col remains snowbound into early summer, making winter and spring approaches serious avalanche terrain. Summer conditions open briefly after July, with the driest, calmest windows in late August and early September. Crowding averages 2.0 year-round, reflecting the col's remoteness and technical prerequisites.
Haeckel-Wallace Col suits experienced climbers and backpackers comfortable with high-altitude exposure, avalanche terrain assessment, and navigation in remote terrain. Visitors plan around snowpack stability, afternoon wind timing, and the logistical demands of multi-day access. Winter and spring ascents require avalanche awareness and rescue capability. The 38 mph maximum wind on record and funneling through the col mean that afternoon traffic is risky; morning starts allow retreat if conditions deteriorate. Low crowding means no parking pressure, but also means self-rescue is the only option.
Nearby alternatives in the Kings Canyon corridor include Shepherd Pass (12,050 ft) to the south and Glen Pass (11,978 ft) to the north; both offer similar remote high-Sierra character but slightly lower elevation and variable snow schedules. The Evolution Basin to the west contains Evolution Pass and other crossing points, all requiring equivalent technical skill and avalanche awareness. Visitors often pair a Haeckel-Wallace Col crossing with traverses through the Evolution drainage or the Inyo backcountry, creating 4 to 7 day high-country loops.
