The Basic Oak - Hickory Forest is fairly abundant in Harpers Ferry NHP. A good place to see it is:

1) the Upper Loop Trail on Bolivar Heights, above (east of) the large fields east of Bakerton Road. In this area, it is abutted by stands of the Successional Tuliptree Forest and the Successional Mixed Deciduous Forest, neither of which are dominated by oaks.

Map tip: To better see where this occurs, go to the interactive map of Harpers Ferry NHP and search for "basic oak."
