Taylor Mountain is a prominent 9,863-foot peak in the Centennial Mountains along the Idaho-Montana border and the Continental Divide. Its summit lies between Clark County, Idaho, and Beaverhead County, Montana, just south of Red Rock Lakes National Wildlife Refuge on Caribou-Targhee National Forest land. The mountain is the fifth-highest peak in its range and has especially steep relief on its north side, rising about 3,060 feet in only 1.5 miles. Its north slope drains toward Upper Red Rock Lake while its south slope drains into Taylor Creek, making it both a hydrologic and political divide. Named for James Madison Taylor, it stands as a striking high point above the Red Rock Lakes country.
