Ogallala Formation Fossil Hunting Trail

Box Butte County’s network of ranch roads cuts through exposed Ogallala Formation, where Miocene-era fossils weather out of the sandstone after every thunderstorm. These two-track roads follow section lines across private ranches (with permission) and BLM land, leading to fossil-rich draws where paleontologists have found three-toed horses, giant camels, and saber-toothed cats. The main route follows Pumpkin Creek drainage, where flash floods regularly expose new specimens in the cutbanks.

Moderate difficulty requiring 4WD in wet conditions, as the bentonite clay becomes impassable when saturated. Best hunting is spring through fall after storms. Landowner permission absolutely required for most productive sites. BLM areas require no permits but fossil collection is restricted. This is legitimate scientific territory—the area produces museum-quality specimens that rewrite North American paleontology. Come prepared with GPS, detailed county maps, and respect for private property.
