Description: This data layer contains two geologic lithology types and two category classes of depth to bedrock. These geologic lithologies are known to contain karst features due to their makeup. The addition of classifying the drift thickness is used to show how the shallower depth of drift usually is more likely to have karst features than the thicker drift areas.
