Exploration of the deepest cave in the municipality of Ocampo, and the recovery of at-risk native American burials, in conjunction with INAH.

1:45 to 2:45pm: George Veni on Robber Baron
Robber Baron Cave is the best known and longest cave in Bexar County. It is owned by the Texas Cave Management Association and contains two federally listed endangered species plus one bat species proposed for endangered listing. Detailed quarterly biological surveys of the cave began in October 2023, all supported by members of the Bexar Grotto. The surveys are the basis for a habitat conservation plan (HCP) for the cave, developed with the US Fish and Wildlife Service. This presentation will show the results of the surveys to date, and discuss what they mean for continued caving, research, and public events at the cave.

2:45 to 3:30pm: Marvin Miller will give and update on the exploration of Dinosaur Cave.
Dinosaur Cave was first mapped by cavers in the early 1960’s but trips were few and the cave is extensive. In 2020 we got the opportunity to fully explore  the cave and do a new survey. We discovered a lower stream level that we are still pushing. This talk covers the current project and state of exploration.

3:30 to 4:15: Joe Mitchell on a new survey technique.
A new cave survey technique is described that is ideal for smaller caves that relies on an iPhone to replace sketching. It greatly speeds up the survey process and allows production of much more detailed and accurate maps.

5:30pm Dinner is served at the pavilion

6pm: Photo Salon and Map Salon awards followed by Auction starts at the pavilion

8pm: Story-telling time or ballad time, depending on interest and talent at the pavilion
