Drive 45 minutes west of Enid, OK and you reach the Glass Mountains State Park. It is small, only 640 acres (1 mi2). Sometimes referred to as the Gloss Hills, their name comes from the sheen and sparkle of selenite crystals, or gypsum. The tops of the mesas are thick with them and appear light gray and green. There are also thin layers of selenite in the red dirt of the Permian soil in these “Shining Mountains”. Click this Google Maps image to do some exploring.
At the lower left of the map is a turnout from highway 412 into a parking lot. From there, you can take the trail up the steep 150 foot climb to the top of the largest mesa.
Roadside entrance sign.
