Atmospheric conditions from valley to peak
Mount Sill is a high peak in eastern California’s Sierra Nevada, near the Owens Valley. It stands in a rugged alpine setting of granite ridges, glaciers, and broad high basins, which gives the mountain a striking and remote feel for hikers and climbers. The best time to go is usually late summer into early fall, when snow has mostly cleared from approach routes and the weather is more settled, though conditions can still change quickly at high elevation.
Summit temperature from 39° to 42°, but feels colder because of the wind. Mostly clear with some foggy periods.
