 Between Three Top, Powell and Green Mountain there are two significant gaps, Mine Gap and Woodstock Gap, the latter of which features a dirt road, Rt 758, from the town of Woodstock to the Woodstock Tower, which sits on the ridge of Powell Mountain.Woodstock Tower offers panoramic views of the town and the Shenandoah Valley and was built by the Civilian Conservation Corps in 1935.Between Powell and Short mountains is Edinburg Gap, a more frequently traveled paved road that offers primary access from the west into Fort Valley.
