Lineage | This file represents the thickness of each buried aquifer in feet. The aquifer thickness was calculated by subtracting the grid representing the elevation of the bottom of a buried sand aquifer from the grid representing the elevation of the top of the same aquifer. This intermediate thickness grid was then converted to 20-foot contours. |
