Nature and history of Bear Cave in San Antonio, Texas explored and explained by Michael Mixerr.

Bear Cave is one of the few caves in San Antonio, Texas that are ungated. Only so much history on Bear Cave is documented online or offline. This news article will explain the history, geology, and biology behind Bear Cave. Michael Mixerr will explain everything.

The passages are primarily spaces between collapsed blocks and the cave wall. All levels pinch in breakdown or flowstone-covered breakdown. Height of these passage vary in size and diameter. These cave walls are flowstone-covered. [Ref: TSS Files, The Caves of Bexar County, 1960]

There are uneven breakdown floors as Bear Cave is located in the Balcones Fault Zone and Edwards Aquifer. All the rooms are not level. There are areas where there are surfaces. So climbers and cavers need to be aware. Bear Cave serves as an animal shelter which is home to spiders, harvestmen (prob. Leiobunum townsendii), snails, bats, cave crickets (Ceuthophilus sp.), and a slimy salamander (Plethodon glutinosus albagula). Wildlife from Mud Creek can be found inhabiting this cave. Bear Cave is just 100 meters away from Cub Cave. [Ref: The Caves of Bexar County, George Veni]

A map of Bear Cave was surveyed by James Jasek in 1964. He discovered that there is a possibility that Bear Cave and Cub Cave connect with each other. That was the first known documentation of Bear Cave. This cave was surveyed again by Allan Cobb and Joe Ivy on August 17, 1985. [Ref: The Caves of Bexar County (Second Edition), George Veni]

Bear Cave is located at 20393 Stone Oak Parkway, San Antonio, Texas, US 78258.
