Cayman Islands

Blowholes are among the most spectacular sights on Grand Cayman and Cayman Brac.1 As waves crash against the islands, water is forced up through tunnels in the rock, and it explodes from the ground in jets of spray up to 20 feet high.2

Despite the awesomeness of this display, blowholes evidence that the Cayman Islands are being slowly eaten away by the sea. The tunnels in the ironshore, the type of rock that forms the islands, have been carved by the very same surf that continues to pound relentlessly against the coast.3
