Marble Falls, Burnet County
Entomologist Ferdinand Lueders made the earliest recorded discovery of this cave in 1821. Notorious in the Civil War era, the hole is believed to have been the dumping ground for up to 17 bodies, including those of pro-Union Judge John R. Scott and settler Adolph Hoppe, several Reconstruction-era county government officials, and Ben McKeever, who had a conflict with local freedmen. An oak tree which once stood over the cave was said to have rope marks caused by hangings. Powerful gases prevented thorough exploration of the site until 1951. The hole was platted in 1968 by the Texas Speleological Society and was found to be 155 feet deep and 50 feet long. (1998)
