Rock School was the longest continuously functioning rural school in Rio Blanco County. The first school was a log building built in 1892. The present building replaced that building and was made of oil shale and sandstone and opened in 1897.

Rock School was the last rural school to close its doors to students in 1990. Even today, it is used by an oil company for offices and the teacherage (Stewart School) next door, is leased to private residents. As of 2013, you can still view this school as you travel along County Road 5.
