APPA HUC10 Shell AEA

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2012-03-01T00:00:00Z
Dataset defines a "zone" around the Appalachian National Scenic Trail (A.T.) that is intended to define an area of interest. The boundary is NOT an ownership map, but is instead a zone around the A.T. that can be used to identify existing data or other information related to the A.T. or that may be useful for describing A.T. resources. The boundary of the dataset was established by selecting all HUC10 watershed that are within 5 statute miles of the A.T. land base. There are 236 HUC10 watersheds within this zone. All 236 watersheds were subsequently merged into a single polygon to create the "shell."
