Today I downloaded the source data from the U.S. Geological Survey Open-File Report 2008-1154 - Preliminary Map of Potentially Karstic Carbonate Rocks in the Central and Southern Appalachian States - and published it as tile and feature services, along with a few maps and apps.
You'll find the layers via search, and you can also view the data in this app which uses the new Basic Viewer template.
