Mount Jefferson is a mountain located on the Continental Divide between Fremont County of northeastern Idaho and Beaverhead County of southwestern Montana. Mount Jefferson is the highest point of the Centennial Mountains, whose crest runs along the Continental Divide and can be climbed using a class 2 route (scramble) from the access road to neighboring Sawtell Peak.

The south and west slopes of Mount Jefferson drain into Hell Roaring Creek, thence into Red Rock Creek, the Red Rock River, the Beaverhead River, the Jefferson River, the Missouri River, the Mississippi River, and into the Gulf of Mexico. Brower's Spring, the source of Hell Roaring Creek, on the mountain's east flank in Montana, is considered the absolute headwaters of the Missouri River.[3] The northeast slope of Mt. Jefferson drains into the South Fork of Duck Creek, thence into Henrys Lake, the Henrys Fork of the Snake River, the Columbia River, and into the Pacific Ocean.
