It's like you're flying when you're standing up here
The Visitor's Center has an awesome view to the east from up on the walkway. On a clear day -- and this day was very clear -- you can see South Mountain, the ridge between the Middletown Valley and the Hagerstown Valley, which is 37 miles away.
The mountain in the background of this picture is Tonoloway Mountain, about 19 or so miles away. I'm not sure if the Tonoloway Limestone is named for the mountain, or vice versa.
