🏔️ Glass Mountains

The Glass Mountains are a group of landforms located in northwestern Oklahoma. They are not actually mountains, but a series of mesas and buttes that are part of the Blaine Escarpment that extends from the Permian red beds in Major County. They rise 150 feet (46 m) to 200 feet (61 m) above the surface of the plains, and the highest elevation in the formation is about 1,600 feet (490 m) above sea level. The Glass Mountains stretch west along U.S. Route 412 from Orienta south of the Cimarron River. The name comes from the sparkling selenite crystals on the slopes and tops of the mesas.
