Ebbetts Pass
Peak · 8,731 ft · Yosemite corridor
Ebbetts Pass is an 8731-foot Sierra Nevada pass in California's Yosemite corridor, sitting on the eastern rim of the range. A high-elevation crossing exposed to afternoon wind and spring snow.
Wind funnels hard across the pass saddle by afternoon, driven by the temperature differential between the high Sierra and the Great Basin. Mornings are measurably calmer. Spring snowpack makes approach treacherous; avalanche terrain is active. Expect sustained 11 mph average winds with gusts to 29 mph.
Over the last 30 days, Ebbetts Pass averaged 11 mph wind with a NoGo Score of 33. Temperature has held near 29 degrees Fahrenheit, typical for April at 8731 feet. The week ahead will show whether afternoon wind builds as usual or if a system moderates the exposure. Watch the score trend: days climbing above 40 mean afternoon access is marginal.

About Ebbetts Pass
Ebbetts Pass lies on California Highway 4, the primary east-west crossing between the Central Valley and the high Sierra's eastern slope. The pass sits 8731 feet above sea level, roughly 30 miles northeast of Sonora and 35 miles south of Lake Tahoe. Highway 4 is the direct route; access from the west via Angels Camp or from the east via Markleeville. The pass marks the boundary between moister westward slopes and the drier Great Basin to the east. In winter and spring, snow closes the route for weeks; CalTrans typically opens the corridor by late April, though early-season conditions are fragile.
The 30-day average temperature of 29 degrees Fahrenheit reflects a place still gripped by high-elevation cold through April. Wind averages 11 mph but frequently exceeds that in the afternoon as the sun heats the valley floors below. The pass sits in full exposure on open ridgeline; there is no sheltered lee, no tree cover to break wind. Crowding remains light (3.0 average) because access is limited by snow and road closures. May through September sees the heaviest use; late April and October are shoulder periods when the road may be marginal but passable. Winter (November through March) is typically closed. Avalanche terrain is present on the higher slopes north and south of the pass saddle; late spring instability is common as the snowpack consolidates and slides off.
Ebbetts Pass is best suited to drivers making the Sierra crossing, not climbers or base campers. The pass itself has no trailhead infrastructure or parking beyond roadside pullouts. Experienced backcountry skiers use the terrain in spring, but only after consulting the Sacramento Avalanche Center forecast. Day trippers should plan morning transit; afternoon wind and whiteouts from afternoon thunderstorms make the afternoon crossing risky. Highway closures due to snow or avalanche control work are routine through May. Peak visibility and stability come late May through mid-September, when the pass is typically open and wind is still moderate by Sierra standards.
Nearby alternatives include Monitor Pass (Highway 89, 8314 feet, south of Ebbetts) and Sonora Pass (Highway 108, 9624 feet, further south), both also high-elevation crossings with similar seasonal closures and afternoon wind exposure. Carson Pass (Highway 88, 8574 feet, to the north) offers a lower and slightly more sheltered route but sees heavier traffic. For hikers and climbers, the Sierra high country accessed from Yosemite Valley via Tioga Pass (9945 feet, Highway 120) is more developed but closes earlier in winter and remains snowbound longer. Ebbetts Pass is the least-hyped and least-crowded corridor through this section of the range; that unpopularity makes it practical only for drivers confident in high-altitude driving and snow navigation.
