What is Corkscrew Cave? An open cave in San Antonio, Texas explored.

Corkscrew Cave is one of San Antonio’s forgotten caves. Corkscrew Cave is one of the estimated 500 caves in San Antonio, Texas. Not much information is known about this particular cave. This news article will explain what Corkscrew Cave is.

Corkscrew Cave is developed in the recharge zone of the Edwards (Balcones Fault Zone) Aquifer. Corkscrew Cave is one of the few caves in Bexar County that provides human access to the local water table. The water level averages 21 meters below the floor of nearby Cibolo Creek (a major stream valley which is usually dry because it loses its water as recharge into the Edwards Aquifer). No research has determined if the recharge water from the cave is maintained in conduit flow or if it disperses into small fractures when under phreatic conditions. Based on the low success rate of drilling productive water wells in that region, the assumption that charge in the Corkscrew Cave area enters and maintains itself as conduit flow is not unreasonable. The consequences of such a low regime should be carefully weighed in considering problems of water quality for the regional groundwater supply.

The Streptocephalus sp. (accidental) of the Streptocephalidae Family has been discovered inside of Corkscrew Cave. (Ref: https://tpwd.texas.gov/business/grants/wildlife/section-6/docs/invertebrates/e1_j54_final_report.pdf)

There is now a gate on the cave which was installed by Central Catholic High School to ensure safety and to protect the integrity of the cave. Corkscrew Cave is open to anyone who signs the proper release form. (Ref: https://digital.lib.usf.edu/content/SF/S0/05/50/21/00001/K26-04572-1973-v18-n05.pdf)
