SAN ANTONIO (WOAI/KABB) - What does it look like inside the cave where an 18-year-old got stuck for more than 10 hours on Thursday?
A year ago, WOAI/KABB went inside Robber Baron Cave for a report focusing on some fascinating air quality research being done by scientists from San Antonio's Southwest Research Institute.
The 'cave' is a maze of long, twisting tunnels, naturally carved into the limestone deep underground by water over eons.
The opening is about 40 feet below most of the area around it - at the bottom of a sinkhole.
Reporter Randy Beamer covered several stories about the cave and describes his experience as "a little unnerving" squeezing into the tight passages. He said while on-site he never felt unsafe because he had the required caving gear and local experts guiding him.
Members of the Technical Rescue Team of the San Antonio Fire Department for their worked in very difficult conditions to safely rescue the teenager late Thursday night. She was stuck for more then 10 hours.
