The Best Cave Discovery in Texas in the Years of 2019–2020

In 1960, cavers checked out a small cave on a ranch near San Antonio, Texas. Other cavers had been there before, but they pushed harder, and made the discovery of some of the largest, best decorated cave passages in Texas. A few years later it opened as a show cave and is well known and very popular. No new passages had been discovered in the cave since the late 1960s.
