Note:  information is subject to change.

The TSA, founded in 1956, has been bringing cavers together from around Texas for over 50 years.  TSA Spring convention is a great time for all of us to come together with family and friends to enjoy group meals, presentations, workshops, new works at the Map & Photo Salon, treasures at the TCMA auction, business meetings, and your favorite vendors.

The spring convention is the annual technical meeting featuring presentations on projects and information on the scientific aspects of caving.

We will be having a catered dinner from Fritz's BBQ in Boerne, TX. They have been really helpful in getting the most food for the most reasonable price. Dinner will include various casseroles (including a vegetarian option), a nice spring mix salad, bread (white and wheat) and tea (sweet and unsweet). There will also be dessert provided by volunteers of an assortment of baked goods for grazing upon throughout the remainder of the evening.


The Chapas Group Camping Area is a secluded section of the park that we will have all to ourselves. It is a nice large grassy field of first come, first serve camping. There is plenty of electric power stations, but no showers and no potable water, make sure to bring your own water. Located on the east side of the park, the Chapas Group Camping is actually very close to a few of the caves on the property and across the way from the picturesque Chiquita Falls.


There will be many scientific and exploratory talks all day on Saturday as usual. In addition, we will also be having several workshops, including survey, sketching, drafting maps in Walls and rigging. They will be held in the field and in cave. Please stay tuned to the event page on FB or the email announcement on CaveTex for sign up for the workshops. They will all have a limit to number of participants and be on a first come, first serve basis. Sign ups will be happening very soon.
