Atlas

Cathedral Mountain at Gloss Mountain State Park in Major County rises 150–200 feet above the surrounding prairie on US-412 between Fairview and Enid. The selenite-capped mesas that give the Glass/Gloss Mountains their name flash silver in direct sun. A short staircase trail (1.2 miles round-trip) climbs Cathedral Mountain for a panoramic view over Lone Peak Mountain and the flat wheat country of northwest Oklahoma. Free access, year-round. The park's roadside pull-out makes it a quick spontaneous stop mid-ride.

// The stop

The mesas here are remnants of a prehistoric inland sea. Over vast stretches of time, softer surrounding rock eroded away, leaving behind harder formations capped with selenite gypsum — the mineral that gives the Glass Mountains their name. These selenite crystals catch and scatter direct light, which is why the slopes look silvered in the early morning or late afternoon sun.

The trail up Cathedral Mountain is a short staircase climb from the roadside parking area, topping out on a flat mesa. From the rim, the view extends across the wheat-country prairie to Lone Peak Mountain and the surrounding valley floor — open in every direction with nothing to interrupt the sightline. Keep an eye out near the rock faces; snakes are present on the terrain, so watch where you step, especially in warmer months. The park is open year-round from sunrise to sunset, admission is free, and facilities at the base include restrooms, picnic areas, and public water — enough to make it a genuine mid-ride break rather than just a rolling pass.

// Why riders stop

The only place in northwest Oklahoma where you get mesa-top elevation with a 360-degree prairie panorama. The selenite crystal caps glinting in low light are a visual you don't get anywhere else in the state. Quick enough to do in 30 minutes, memorable enough to plan around.

Arbuckle Mountains — US-77
Oklahoma
North of Springer, US-77 leaves the interstate corridor and reverts to a narrow two-lane highway as it enters the Arbuckle Mountains — one of the oldest exposed mountain ranges in North America. The road was paved in the 1920s using prison labor and retains its original alignment through tight hairpin curves and wooded limestone terrain. The route provides direct access to Turner Falls Park (Oklahoma's tallest waterfall at 77 feet) and continues through Davis. Rider Magazine describes this hairpin section as a highlight of the greater Arbuckle region ride.

Cherokee Hills Byway (OK-10)
Oklahoma
Oklahoma's Cherokee Hills National Scenic Byway (designated 2009) runs 84 miles along State Highway 10 from Gore north through Tahlequah to West Siloam Springs on the Arkansas border. The southern half traces the eastern shore of Lake Tenkiller through forested Cookson Hills, while the northern stretch parallels the clear waters of the Illinois River past stone bluffs and dense Ozark foothills. OK-10 through the Tahlequah corridor is noted for long, flowing sweepers, limited sight lines around blind wooded corners, and consistent tree canopy. The Cherokee Nation capital at Tahlequah is on-route.

Glass Mountains — US-412
Oklahoma
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.
