L-A-D Foundation - Land Stewardship in the Missouri Ozark Highlands Since 1962
Video--Karst in Perry County
This documentary investigates a Missouri county's karst features--caves, sinkholes, sink basins, and springs--and reports on a county-wide controversy that erupted when a cave-dwelling fish, the grotto sculpin, was considered for listing as an endangered species.
This video was produced in 2020 by Denise Henderson Vaughn, Somewhereinthewoods Productions, and the Ozarks Resource Center, with funding from the L-A-D Foundation.
Ozark underground mysteries are further explained in “Karst in the Ozarks,” a companion documentary by the same producers. It features Grand Gulf, Greer Spring, and Tumbling Creek Cave to show how groundwater in Ozark caves and springs is vulnerable to pollution.
