Ritter-Banner Saddle
Peak · 12,025 ft · Yosemite corridor
Ritter-Banner Saddle is a 12,025-foot pass in the Yosemite corridor's high Sierra, linking the Ritter and Banner peaks. Wind funnels across the saddle in predictable afternoon surges; exposed ridgeline terrain demands strong route-finding and avalanche awareness in winter.
Wind dominates. Morning hours are calmer; afternoon gusts accelerate off the adjacent peaks and exposed ridgeline. Average wind runs 12 mph over the past month, with isolated gusts to 33 mph. Temperature hovers near 22 degrees Fahrenheit on a 30-day average. Snow patches persist into summer; navigation becomes straightforward only once melt exposes rock and scree.
Over the last 30 days, Ritter-Banner Saddle has averaged 12 mph wind and a NoGo Score of 34, with peaks to 33 mph and lows dipping to 6. The week ahead will track similar patterns: expect afternoon wind acceleration and sustained cold at elevation. Plan movement for early daylight; afternoon crossings carry higher risk of exposure and wind-driven navigation error.

About Ritter-Banner Saddle
Ritter-Banner Saddle sits at 12,025 feet on the ridgeline between Mount Ritter (11,155 ft) and Mount Banner (12,945 ft), deep in the Yosemite corridor's backcountry. Access routes converge from the Mammoth Lakes area and from Yosemite Valley via Highway 120 and Highway 395. The primary approach climbs from the Mammoth Lakes gateway, typically a full day's travel from the trailhead. The saddle itself is not a destination summit but a critical pass on multi-day traverses; few visitors approach it as a standalone objective. Winter and spring approaches require a shuttle or staged logistics due to road closures on Highway 120 east of Tioga Pass.
Conditions at Ritter-Banner Saddle reflect extreme alpine exposure. Average wind over 30 days stands at 12 mph; gusts exceed 33 mph during pressure systems or afternoon heating cycles. Temperature averages 22 degrees Fahrenheit and can drop below 8 degrees on the 365-day low. Crowding remains light (average 3 on the NoGo scale) because the saddle attracts only experienced mountaineers and traversers. Late spring through early autumn see the highest activity; winter and early spring route-finding is complex due to snow and avalanche terrain. Afternoon wind acceleration is reliable enough to anchor planning; morning crossings are calmer and safer.
Ritter-Banner Saddle suits experienced alpine trekkers and mountaineers comfortable with class 3-4 scrambling, exposed ridges, and self-rescue. Parties typically include this pass as one leg of a 3 to 5 day Sierra traverse. Water sources are infrequent near the saddle itself; most approach climbs rely on melt-fed streams lower on the massif. Avalanche terrain surrounds the saddle on approach gullies and corniced ridges; winter and spring travel demands current avalanche forecasts from the Shasta Avalanche Center. Afternoon wind is the dominant concern for day travel; fatigue, exposure, and navigation error compound in afternoon hours when wind peaks. Early starts are non-negotiable.
Nearby alternatives include Banner Peak (12,945 ft) and Mount Ritter (11,155 ft), which can be climbed from the same approach basins but avoid the exposed saddle crossing. The Mammoth Lakes region offers lower-elevation alpine passes and summer-accessible watersheds if snow or wind conditions force a retreat. Lake Crowley and Horseshoe Lake provide water access and camping near Highway 395, cutting approach time by a half day. For Yosemite Valley visitors, the Tenaya Lake corridor and Tuolumne Meadows provide analogous high-country exposure at slightly lower cost in wind and driving time.
