Blacktop Peak
Peak · 12,732 ft · Yosemite corridor
Blacktop Peak rises to 12,732 feet in the Yosemite corridor's high Sierra. A windswept summit above glacial basins, it demands respect for avalanche terrain and unpredictable afternoon gusts.
Wind dominates here. The 30-day average sits at 14 mph, but gusts routinely spike to 40 mph by afternoon as warm air funnels upslope from the valley. Morning calm is brief. Expect temperatures in the low teens Fahrenheit and thin snow coverage even in spring. Terrain steepens sharply on the northeast face.
Over the last 30 days, Blacktop Peak averaged a NoGo Score of 33 with wind around 14 mph and temperatures near 18 degrees Fahrenheit. The week ahead follows the typical pattern: coldest at dawn, windiest from mid-afternoon onward. Watch for sudden gusts and unstable snowpack on steep north-facing slopes where avalanche terrain is prevalent.

About Blacktop Peak
Blacktop Peak sits at 12,732 feet in the Yosemite corridor, north of Mono Pass and south of the Sierra crest proper. Access is via Highway 120 from the west (Lee Vining approach) or Highway 395 from the east. The peak lies roughly 2 to 3 hours' drive from Mammoth Lakes or Yosemite Valley depending on snow and road conditions. Winter and early spring access often requires chains or four-wheel drive; Highway 120 closes seasonally. The peak is a scramble-plus destination, not a technical climb, but the high altitude and avalanche terrain demand experience with snow and rockfall hazard assessment.
Blacktop Peak's weather is shaped by its elevation and exposure to the Sierra's dominant westerly flow. The 30-day average temperature hovers at 18 degrees Fahrenheit, with the rolling 365-day range from a low of 3 degrees to a high of 29 degrees. Average wind runs 14 mph, but maximum gusts reach 40 mph consistently; afternoons are reliably windier than mornings. Crowding averages 3 out of 10 because the approach is remote and few peak-baggers detour this far north. Snow typically persists through late spring, though depth varies year to year. Avalanche terrain covers the steeper northeast and north-facing drainages; the SAC avalanche center issues forecasts for this area.
Blacktop Peak suits experienced alpinists and peakbaggers comfortable moving on steep snow and loose talus. Parties should plan for the afternoon wind by starting before dawn and summiting by early afternoon. Lack of water and exposed campsites limit car camping nearby; most climbers base out of Mammoth Lakes or Lee Vining. Parking at trailheads fills quickly on weekends in spring and early summer. The low base popularity (0.2 rating) means solitude is the norm, but it also means minimal rescue infrastructure. Anyone attempting the approach should carry a beacon, probe, and shovel, and check the SAC forecast immediately before heading out.
The area sits in the transition zone between the Sierra's wet western slope and the rain-shadow east side. Blacktop Peak is colder, windier, and more avalanche-prone than the more-traveled Mammoth corridor peaks to the south. It is safer and more predictable than the exposed ridges directly on the crest. The Mono Pass area to the north offers similar elevation and terrain but slightly better-sheltered camp options. Late September through early October brings the most stable snow and clearest skies; wind is still present but temperatures climb into the 20s Fahrenheit on good days.
