Mining the Limestone – Two Praries, One Place
The burned oyster shells produced lime which was the binding agent or mortar in "tabby.". Lime was produced locally in Kasota by the calcination or burning of limestone at a very high temperature in a kiln. As far as I know, no "sticky rice" was added. There is at least one remnant of a lime kiln on the Kasota Prairie.

Environmental Hazards of Limestone Mining | Sciencing
In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which …
