HARKEY KNOBS. The Harkey Knobs, a range of hills with elevations of about 1,470 feet above sea level, are four miles southeast of Algerita in central San Saba County (at 31°11' N, 98°50' W). They stand in generally flat terrain with localized dissection, surfaced by clayey loam soils that support mesquite, Ashe juniper, live oak, and grasses. The hills were named for Billy Harkey, an early settler.
