Initially, the town was named "Independence", because it was founded on July 4th in 1862.
The postal authorities said no, because there was already a town by that name in Oregon. So they chose "Granite", for the prevailing rock of the region.
Granite had four stores, five saloons, and two hotels. One of them, the Grand Hotel, had forty-two rooms.
The mines in the region produced gold for decades, but then, Granite declined. The Grand Hotel served meals until the late 1930s. It was destroyed in 1943. The post office closed in 1957.
