MONTANA — From glacier-carved cliffs to sandstone pillars etched by wind and time, Montana’s dramatic terrain is home to some of the most striking geological features in the United States.
While some require hours of rough driving or backcountry hiking, these rock formations prove that the reward is worth the challenge.
Here are ten breathtaking formations that blend natural history, adventure, and unforgettable views.
1. Medicine Rocks State Park — Ekalaka
Tucked into southeastern Montana, Medicine Rocks showcases sandstone formations full of arches, holes, and tunnels, sculpted by millennia of wind and water. This site is also rich in cultural significance, with Indigenous petroglyphs and settler-era carvings still visible in the stone.
2. Terry Badlands — Terry
The Terry Badlands Wilderness Study Area is a geological marvel made up of banded sandstone bridges, tabletops, and pinnacles. The remote and undeveloped terrain offers vivid colors at sunrise and sunset, making it ideal for both solitude and photography.
3. Ringing Rocks — Near Butte
Just east of Butte lies a boulder field where certain rocks emit bell-like tones when struck. Known as Ringing Rocks, the site is freely accessible and open year-round, providing a rare interactive geologic experience.
4. Pryor Mountains — Southern Montana
Rising suddenly from the plains, the Pryor Mountains offer rugged canyons, ice caves, and limestone cliffs. This formation contrasts with the glacier-shaped peaks in western Montana and supports unique wildlife and ancient rock layers.
5. Pompey’s Pillar — Nibbe
This 130-foot sandstone tower is one of Montana’s most famous historic landmarks. William Clark of the Lewis and Clark Expedition carved his name into the rock in 1806, a signature that remains visible today.
6. White Cliffs — Fort Benton
Floating along the Missouri River, adventurers will encounter the White Cliffs, where white sandstone pillars are capped with dark earth. These formations were described by Meriwether Lewis as both “romantic” and “remarkable.”
7. Rock City — Valier
Near Valier lies Rock City, a quiet collection of mushroom-shaped hoodoos and flat-topped rock clusters. Off the beaten path, this area offers an uncrowded escape into the Montana badlands.

8. Makoshika State Park — Glendive
Montana’s largest state park, Makoshika, features dramatic hoodoos, canyons, and fossil-rich sediment. The terrain dates back to the Cretaceous period, making it a favorite for geology buffs and dinosaur hunters alike.
9. Ice Caves Trail — Big Snowy Mountains
For the well-prepared hiker, the Ice Caves Trail in the Big Snowy Mountains leads to year-round frozen caves perched atop a ridge. The challenging ascent rewards trekkers with views of central Montana’s mountain ranges and a rare glimpse of subterranean ice even in summer.
10. Granite Peak — Beartooth Mountains
Towering at 12,799 feet, Granite Peak is Montana’s highest summit. Made of ancient rugged granite, the climb is considered one of the toughest in the state, but those who reach the top enjoy panoramic views and a true wilderness triumph.
