Echo Peak #9
Peak · 10,846 ft · Yosemite corridor
Echo Peak #9 is a 10,846-foot summit in the Yosemite corridor of California's Sierra Nevada. Avalanche terrain demands winter caution; exposed ridge and wind tunnels define conditions.
Wind rises sharply in afternoon hours, funneling off the snow-covered slopes to the north. The 30-day average wind of 12 mph masks frequent gusts above 25 mph after 1 PM. Morning windows are narrow and calm; mid-day onwards, plan for sustained exposure.
Over the last month, conditions averaged a NoGo Score of 32, with temperatures holding near 24 degrees Fahrenheit and the 30-day average wind at 12 mph. The week ahead will track similar patterns: early calm, afternoon deterioration. Winter snowpack is relevant; avalanche terrain above 10,000 feet demands current SAC bulletins before departure.

About Echo Peak #9
Echo Peak #9 sits at 10,846 feet in the high Yosemite corridor, east of the main park valley. Access is via Highway 120 from the west or Highway 395 from the east; the peak is typically approached from trailheads near Tenaya Lake or the eastern Sierra. Drive time from the Highway 395 corridor is 30 to 45 minutes depending on snow gates and seasonal closure. The location sits on the divide between Tenaya Canyon and the Mono Basin, exposed to both west-moving storm systems and the föhn wind from the Great Basin.
Seasonal patterns at Echo Peak #9 are controlled by snowpack and wind exposure. Winter and early spring bring deep snow, avalanche hazard, and temperatures averaging 12 to 38 degrees Fahrenheit across the year. The 30-day average temperature of 24 degrees Fahrenheit reflects late April conditions near the snowline. April through early June, melting accelerates and wind becomes the primary constraint; the 30-day average wind of 12 mph is typical, but sustained gusts reach 33 mph on exposed days. Late June through August sees reduced snow, moderate temperatures, and lighter afternoon winds. Crowding remains low year-round; the base popularity score of 0.2 reflects limited foot traffic even in peak summer.
Echo Peak #9 suits mountaineers, ski tourers, and experienced ridge travelers. The avalanche terrain demands competency in slope assessment and snow conditions interpretation; consult the SAC avalanche center before any winter or spring approach. The ridge itself is loose and exposed; high winds create cornices and dangerous exposure. Summer ascents via the eastern approach face less snow but exposed scrambling and afternoon electrical risk. Parking near trailheads fills early on stable-weather weekends; plan to start before dawn if timing a weekend trip. Water sources are snowpack-dependent; carry at least two liters and be prepared to melt snow in spring.
Nearby alternatives in the Yosemite corridor include Cathedral Range peaks to the southwest and the Mono Basin crests to the east. Echo Peak #9 differs from Cathedral Peak in being higher, more remote, and less developed for casual visitor traffic. The eastern approach from Highway 395 is faster but exposes you to Mono Basin wind regimes; the western approach from Tenaya Lake is longer but offers slightly more shelter. Experienced Sierra travelers often pair Echo Peak #9 with neighboring summits on a multi-day traverse; the low base popularity means solitude but also means minimal trail infrastructure and rescue resources.
