Karst country: caves, springs, and sinkholes shape Pulaski land

Karst is easy to miss on Pulaski land: the clue may be a spring, a losing stream, a cave opening, or a bowl-shaped sink in a pasture. In Missouri karst, groundwater dissolves limestone and dolomite over time. That hidden work makes caves, springs, sinkholes, and streams that can drop into the ground.

For rural property, the concern is plain. Water on the surface and water underground can be closely tied together, so a spill, a bad drain, or a poorly placed septic system may travel farther than expected. A sinkhole is not just a low spot to fill; it can keep acting like a natural drain after it forms.

GeoSTRAT is the useful map table before a well, septic layout, driveway, or basement plan. It can point to known springs, mines, sinkholes, and other geologic data, then a landowner can bring the exact parcel question to a registered geologist, engineer, or the Missouri Geological Survey.
