 Another narrow gap separates Fort Lewis Mountain from Little Brushy Mountain, a small 1,926 foot high peak, which is located in Roanoke County just north of Salem, Virginia.The mountain, which had been called Butler Mountain on its west side and Deyerle Mountain on the east, was renamed for Fort Lewis, an early 19th-century fort which was located in western Roanoke County just outside the current city limits of Salem.The fort was named after Andrew Lewis, a colonial era general who lived in the area.
