|Pottsville Formation, Black Warrior Basin, Alabama/Mississippi
The sequence is deeper to the southwest. The structural map by Borland and Minihan (1977, in Hewitt, 1984), was gridded to represent this property in the GIS data base. We used the DEM generated from National Imagery and Mapping Agency (2000) to calculate and grid the depth to top Pottsville (c1pottsville).
