The Hole shared by @afar says: ""The Hole is a geologic formation that offers a dramatic look at the same karst process that created Conch Bar Caves and other limestone sinkholes and caverns found throughoutthe Turks and Caicos Islands. As its name implies, the Hole is area'slargest limestone sinkhole, about 60 feet deep and 50 feet across. A pool of water at the bottom connects to JubaSound's nearby pondsthrough an underground tunnel. You can rent a car and drive to the Hole on the east side of Juba Sound; however, use caution when walking near the edge, as limestone can crumble."" on Postcard
