Yes, it's a gas station. You can get gas, ice, and souvenirs. You can also order lobster taquitos, and their world famous fish tacos. Seriously good.

Mount Sill is one of the fourteeners of the Sierra Nevada in California. It is located in the Palisades, a group of striking rock peaks with a few small glaciers on their flanks. Mount Sill is located 0.6 miles (1 km) east of North Palisade, the high point of the group. The two peaks are connected by a high, rocky ridge, on the north side of which lies the Palisade Glacier. Mount Sill lies on the main Sierra Crest, but is at a point where the crest turns sharply, giving it particularly striking summit views. On one side is Kings Canyon National Park and Fresno County; on the other is the John Muir Wilderness, Inyo National Forest and Inyo County.
