Pryor Mountains, Mountain range in Montana, United States

The Pryor Mountains are a limestone range in southern Montana, near the Wyoming border, with East Pryor Mountain as the highest point. The terrain mixes open plateaus, deep canyons, and grassy slopes where wild horses roam freely.

The range takes its name from Sergeant Nathaniel Hale Pryor of the Lewis and Clark Expedition, who came into this area while tracking stolen horses in the early 1800s. Long before that, the Crow people had lived in and around these mountains for generations.

The Crow people call these mountains Baahpuuo Isawaxaawuua, meaning Hitting Rock Mountains, after the flint deposits found here that were shaped into arrowheads. This name shows how directly the land provided what people needed for everyday life and hunting.

Most access routes into the range run along unpaved forest roads, which can become difficult to navigate after rain or in winter. Mornings tend to offer the clearest conditions for exploring the higher terrain.

The limestone caves in the Pryor Mountains shelter ten different bat species, which makes this the most varied bat habitat in the whole state of Montana. These underground passages run beneath the same slopes that look so open and bare from above.
