Wurzbach Bat Cave Preserve

Wurzbach Bat Cave is a significant cave in the city of San Antonio. Formed in the Austin Chalk, it has 589 meters (1,932 feet) of currently mapped passage. The cave formerly housed a colony of tens of thousands of Cave Myotis (Myotis velifer), which unfortunately became the victim of the previously uncontrolled visitation, and inadvertently poorly-designed (but secure!) gates. There are also records of at least 43 other animals using the cave, including the Federally Endangered cave beetle, Rhadine infernalis. The cave takes water, but its resurgence is unknown. The lowest level of the cave, which is approximately 22 meters (72 feet) below the surface, is accessed through a tight pit with reported bad air, and has not been pushed to the end.
