Monitor Pass (el. 8,314 ft / 2,534 m) is a high mountain pass in California in the Sierra Nevada southeast of Lake Tahoe. It is traversed by State Route 89 near that highway's southern terminus at U.S. Route 395 near the community of Topaz. While this section of Route 89 serves to connect the basins of the West Walker River and Carson River, Monitor Pass itself lies on a side ridge between tributaries of the East Fork Carson River. Crossing the pass allows for a more direct route between U.S. 395 and Markleeville, California, at the expense of some additional elevation.
