We drove out to Winchester a couple weeks ago (a helpful middle meeting ground between Staunton and DC to pick up my daughter when she stays with my parents lol), and I was surprised that the elevation on the east side of the BR was basically the same as the west heading towards Winchester. The valley is so much lower around Winchester than around Staunton and points south. In Rockbridge County it actually goes above 1800' until it starts descending as you head towards Roanoke.
