Split Pinnacle
Peak · 5,049 ft · Yosemite corridor
Split Pinnacle rises to 5049 feet in the Yosemite corridor of California's Sierra Nevada. This exposed alpine peak sits in avalanche terrain and demands winter caution and stable snowpack.
Wind accelerates through the ridgeline by early afternoon, funneling off the eastern slopes. Morning hours run calmer, typically 5 to 8 mph before thermals kick in. Exposure is complete; there is no shelter on the summit approach. Snow lingers well into late spring.
Over the last 30 days, the average wind at Split Pinnacle has been 7 mph, with gusts reaching 17 mph on exposed days. The average temperature sits at 41 degrees Fahrenheit and crowding remains light at 3 on the 10-point scale. The week ahead should track similar conditions; watch for afternoon wind spikes and monitor snowpack stability before any winter or early-spring approach.

About Split Pinnacle
Split Pinnacle stands in the high-Sierra Yosemite corridor between Tioga Pass and Yosemite Valley, accessed via Highway 120 from the east or Yosemite Valley roads from the west. The peak sits at 5049 feet on a ridgeline east of the main crest, making it a secondary summit in a backcountry chain rather than a roadside pullout. Winter and spring ascents require snowpack assessment and avalanche awareness. Base popularity is low (0.2 on NoGo's scale), meaning solitude is the norm unless conditions trigger a surge in backcountry traffic.
Conditions here mirror the exposed high-Sierra profile: consistent afternoon wind, cool temperatures year-round (37 degrees average in the 365-day window, peaks near 62 degrees in summer, dips to 7 degrees in deep winter), and rapid weather swings. The 30-day average wind of 7 mph masks afternoon gusts that regularly hit 17 mph. Spring brings the most variable snowpack and highest avalanche risk. Summer sees stable snow melt-out and afternoon thunderstorm exposure. Fall and early winter can offer calm, clear days before heavy snow closes the corridor.
Split Pinnacle suits mountaineers and experienced winter climbers planning a high-Sierra winter or spring ascent. Crowds are minimal year-round, but that lightness demands self-sufficiency. Parking is limited in the Yosemite corridor; plan arrival before dawn if visiting on a weekend. Bring avalanche gear and beacon if approaching in winter or early spring. Afternoon wind and exposure make summit time-sensitive; climb early, descend before thermals peak. The nearest services are at Tuolumne Meadows or Yosemite Valley, 30 to 45 minutes away depending on entry.
Nearby peaks in the corridor include Cathedral Range summits to the west and the Lyell-Darwin crest just south. Mono Basin peaks east of Tioga Pass offer similar alpine exposure with slightly lower approach complexity. For those seeking less technical high-Sierra terrain, the meadows and lakes around Tuolumne Meadows provide shelter and easier access while maintaining the same elevation and season-driven constraints.
