Caves of the water sinks depression

Abstract

The Water Sinks Depression is a large closed depression at the northeastern end of Burnsville Cove. It is the final sink point for several surface streams. Two modest-size caves, Owl Cave and Water Sinks Cave, were known earlier. In November, 2007, a collapse revealed a much larger lower level of Water Sinks Cave. The new cave consists of a large master trunk passage, the Water Sinks Subway, and an array of other passages with the characteristics of a floodwater maze. A description of the caves is given along with a detailed description of the exploration of the Subway section.
