Formations in the "Cave Without a Name," located near Boerne in Kendall County, Texas. It has been commercially operated as a show cave and open for public tours since 1939. The cave went largely unnoticed again until the 1920s during the era of Prohibition when a small moonshine distillery was installed in the uppermost cavern. It again fell into obscurity until three local farm children rediscovered the sinkhole in 1935. The show cave received its name after its official opening in 1939, when a young boy suggested that the cave "was too beautiful to have a name." Original image from Carol M.
