Most of the park is higher: NPS lists campground elevations from 3,000 ft at Cottonwood to 4,500 ft at Sheep Pass, and the park reaches 5,814 ft. Expect cooler days and colder nights up there than these station normals show. NPS says winter nights freeze and it occasionally snows at higher elevations. The station publishes no snowfall normal, so snowfall is shown as not reported. This is a preview station, pending full station review.
