From Wiki: Fort Valley is a mountain valley in Shenandoah County, Virginia. The so-called “valley within a valley” lies between the two arms of the northern Massanutten Mountain range in the Shenandoah Valley. The valley is closed at both ends (except for a very narrow gap at the northern end through which Passage Creek flows and a single road, S.R. 678, runs) but opens out as one moves toward the center, becoming about three miles wide at its widest. In all, Fort Valley is 23 miles long.
