Drilling Through Caves and Aquifers

All of northwest Arkansas is karst. The National Cave Association website describes karst as a geological term for an area characterized by the presence of caves, sinkholes, aquifers, and disappearing streams. According to tour guides at War Eagle Cavern there are over 2000 documented caves in north Arkansas alone with over 10,000 documented caves throughout all of Arkansas.

There is a river in Missouri that disappears and then reappears in Arkansas at Mammoth Springs. Determining where water flows underground in northwest Arkansas requires dumping dye into the water at one location then searching for springs and searching for that dye by educated guess work. The dye can be found surprising numbers of miles away.

For a better understanding of aquifers look at the United States Geological Survey (USGS) under Water Science for Schools.

Consider watersheds in general. How can puncturing the ground a mile deep in multiple places not make bedrock permeable?
