Cascade Caverns is a historically, geologically, and biologically important limestone solutional cave south of Boerne, Texas, United States, on 226 Cascade Caverns Road, in Kendall County. It has been commercially operated as a show cave and open for public tours since 1932. ==History== Cascade Caverns is part of the Glen Rose Formation, a shallow marine to shoreline geological formation from the lower Cretaceous period. This formation has been exposed in a large area beginning in South Central Texas, running north through the Texas Hill Country, ending up in North Central Texas. The cave has been open to the environment for many tens of thousands of years, as evidenced by prehistoric animal finds and Lipan Apache artifacts from the 1700s. The cave was first commercially opened in 1932 and operated until about 1941. During the time of closure, the cave's artifact collection was looted. It was later reopened in the 1950s. Cascade Caverns had been originally known as Hester's Cave. It became most famous as a result of Frank Nicholson's publication of cave explorations.〔A.
