LaBarge Rock is a prominent dark pillar on Montana’s Missouri River in the White Cliffs, rising 150 feet above the water and standing out from the surrounding pale sandstone and shale. Named for steamboat captain Joseph LaBarge, it recalls the nineteenth-century river trade that linked lower Missouri ports with Fort Benton and Montana’s mining camps and ranches. The formation itself is an igneous intrusion created about 66 million years ago, exposed by uplift and erosion. Lewis and Clark camped opposite it in 1805, and Karl Bodmer later depicted the scene in 1833. Its remote setting preserves a Missouri landscape little changed since early exploration and river travel.
