Wide Awake Grocery Building

It was deemed notable as "one of the dwindling number of cut stone commercial buildings left in the state. Its architectural importance is enhanced because it displays both rock faced and dressed sandstone ashlar; sandstone, the later type is not normally found." It was also deemed notable as "an important grocery for Belle Fourche since its construction." It was originally Wide Awake Grocery, then Pomeroy and Glassie, and as Sly's from 1922 on.
Over the years its second floor has served as apartments, as a high school, and as a theatre and site of Belle Fourche social events.
The Belle Fourche Commercial Historic District, NRHP-listed in 1982, included it as a contributing building.
