Milestone Mountain is a thirteener on the Great Western Divide,[1] a subrange of the Sierra Nevada. The summit marks a point on the boundary between Sequoia and Kings Canyon national parks. It is 0.6miles south of Midway Mountain and northeast of Triple Divide Peak. It takes its name from the shape of the obelisk on its peak, and has been called this since at least 1873.[4]
