Dead Man’s Hole. The cave achieved notoriety during the Civil War as a dumping place for the bodies of Union sympathizers. During the Civil War, Central Texas proved a dangerous place for those who didn’t cotton to secession. Unionists, as they came to be called, found themselves on the open season list. Some of them, according to once-whispered stories, ended up at the bottom of Dead Man’s Hole. (Mike Cox) N30 31.905, W95 15.594
