Oyler Mine

Overview

A short detour off the Scenic Drive delivers a genuine slice of Capitol Reef history: the Oyler Mine. Set right by the mouth of Grand Wash, this small historic uranium site is more mood and story than spectacle—great for geology buffs, history lovers, and anyone who appreciates a quiet, quirky stop between bigger hikes.

What You’ll See

• Two gated mine adits set about 14 feet apart in the cliff base, each roughly 6.5 by 8 feet and extending about 108 feet into the rock.
• Remains of two unfinished stone buildings near the adits.
• The dramatic cliff face and slickrock that frame Grand Wash.

History

Discovered in 1901 and later revisited during the 1950s uranium boom, Oyler became a touchstone in the park’s mining story. Despite the attention, the actual payoff was tiny—the total royalties from uranium mining in the park added up to just $13.50. Today the site is preserved as a historic resource and kept closed to protect visitors and wildlife.

Geology

This is classic Colorado Plateau uranium country: ore seams appear as dark bands within local sandstones. The mine’s walls were studied in detail, making Oyler one of the best-documented small prospects in the area and a handy reference point for understanding the park’s stratigraphy.

Wildlife

Bats use the mine, which is why the gates are designed to let them pass freely. You might also spot lizards and birds in the surrounding slickrock habitat.

Safety and Etiquette

Do not enter the tunnels—they’re gated for good reason. Avoid touching rock or debris right at the adits; uranium residues can elevate background radiation levels. Give bats space and skip shining lights into the openings.

Is It Worth Your Time?

If you’re into mining history or geology, yes—it’s a quick, low-effort stop with real character. If you’re chasing big views and marquee hikes, you’ll probably treat this as a brief curiosity on the way to Grand Wash or Cassidy Arch.

Best Time to Visit

Early morning or late afternoon gives the cliff face softer, more photogenic light. It’s usually a low‑crowd stop any day of the week, and pairs naturally with nearby hikes when you’re already in the area.
