Regulation Peak
Peak · 10,570 ft · Yosemite corridor
Regulation Peak rises to 10,570 feet in the Yosemite corridor of California's Sierra Nevada. A high-alpine destination exposed to afternoon winds and winter avalanche terrain, it demands clear conditions and stable snowpack.
Wind averages 11 mph but funnels to 30 mph in afternoon thermals off the surrounding basins. Morning calm windows close by midday. Temperatures average 25 degrees Fahrenheit; expect colder, more stable conditions at dawn. Crowding stays low; solitude is the norm here.
The 30-day average wind of 11 mph and NoGo Score of 34 mark Regulation Peak as a marginal-conditions destination through spring. The week ahead shows the typical pattern: cold stable mornings, rising wind and instability by afternoon. Temperature swings from 11 to 39 degrees across the rolling year signal winter snowpack hazard and rapid spring thaw. Monitor avalanche advisories from the Sierra Avalanche Center before any winter or early-season approach.

About Regulation Peak
Regulation Peak sits at 10,570 feet on the spine of the Yosemite corridor, northeast of the main valley complex and accessed primarily via Highway 120 (Tioga Pass route) or the eastern Sierra gateways around Lee Vining. The peak itself lies in avalanche terrain; approach requires travel through steep slopes and corniced ridges typical of the high Sierra crest. Base popularity is low; this is not a marked or heavily signed destination. Nearest trailheads are accessed via Highway 395 from the east or Highway 120 from the west; drive times from Mammoth Lakes or Tuolumne Meadows exceed 2 hours depending on snow conditions and road status.
Regulation Peak's weather is shaped by its elevation and exposure. The 30-day average temperature of 25 degrees Fahrenheit reflects mid-to-late spring conditions on the crest; the rolling 365-day minimum of 11 degrees and maximum of 39 degrees show the harsh winter gradient and late-spring thaw common at this altitude. Wind averages 11 mph but regularly reaches 30 mph in afternoon thermals funneling off the eastern and western slopes. Crowding averages only 3 people across the rolling 30 days, meaning this peak sees traffic primarily from winter mountaineers and spring ski-mountaineers during stable snowpack windows. Late snowmelt (often into June) and avalanche exposure make early-season ascents risky; stable conditions cluster in clear autumn windows and brief high-pressure systems in spring.
Regulation Peak suits experienced alpinists and ski mountaineers familiar with avalanche terrain and self-rescue. Summer and early autumn are safest for non-technical approaches; winter ascents demand avalanche education, current SAC advisories, and proper belay gear. The low crowding makes this a destination for solitude seekers willing to navigate unmarked terrain and manage their own logistics. Typical visitors are climbers moving between multiple peaks on the crest or skiers linking high-altitude traverses. Wind and afternoon instability dominate the planning constraint; head here on clear early mornings and expect to descend before thermals strengthen. Spring ascents require avalanche beacon, probe, and shovel; check the Sierra Avalanche Center forecast before every trip.
Nearby alternatives in the Yosemite corridor include Cathedral Peak (higher, more popular), Clouds Rest (lower, easier access), and the broader Cathedral Range peaks accessible from Tuolumne Meadows. Regulation Peak's isolation and avalanche terrain make it less forgiving than these neighbors; it rewards experienced parties with solitude and unobstructed views of the high-Sierra spine. The trade-off is clear: lower crowds, higher commitment.
