Glass Mountains — US-412
US-412 between Orienta and Fairview in Major County traverses roughly 25 miles of selenite-capped mesas known as the Glass (or Gloss) Mountains, where crimson and black mesa walls rise abruptly from the surrounding wheat-field prairie. The gypsum and selenite crystals covering the mesa slopes reflect sunlight and create a visual signature unique in the southern plains. Gloss Mountain State Park, on a mesa just west of Orienta, provides a walk-up overlook accessible from a roadside pull-out. The highway is a long, flowing two-lane with minimal traffic and unobstructed views across northwest Oklahoma.
