About the photo: Devil’s Sinkhole in Edwards County, Texas taken by Geary Schindel and Benjy Von Cramon in 2017. The photo features Tom Rogers ascending the 145-foot pit. We were in the cave with permission from the owner to perform some water studies. The photo took 2nd place in the National Speleological Society’s (NSS) Photo Salon at the 2023 NSS Convention and the pit was also featured by the BBC and registered millions of views. Tom Rogers was a long-term and very active member of the Bexar Grotto who passed away a few years ago from an unexpected short-term illness.
Bexar Grotto is a diverse group of people passionate about cave exploration, conservation, preservation, and recreation.

About Bexar Grotto
Bexar Grotto is a San Antonio-based non-profit caving organization. Since 1983, we have taken on uncounted projects to explore, restore and conserve caves in and around Texas and to educate the general public on the importance of cave ecosystems, aquifers, and bats.
Our members range from total beginners to experienced international expedition cavers. We have regular meetings, trips, parties, restoration projects and training. We also participate with other grottos and volunteer with cave related organizations to support preservation and conservation efforts.
EXPLORATION
The Grotto regularly ridge walks for new caves, explores, surveys, and maps known and newly discovered caves.
VOLUNTEER
We volunteer for conservation and preservation projects for private landowners and government-owned caves.
EDUCATION
Upon request, the Grotto offers educational presentations and cave trips for schools and formal active organizations.
RECREATION
Throughout the year, the Grotto plans trips for every skill level, for beginners to water caves and caves that require rope skills.
