Mexico
Sistema Tortuga
Located on the same road as Vaca Ha, the entrance to Tortuga can be found after driving the jungle road seemingly forever until it stops at the pool of water somewhat larger than Vaca Ha. The cave starts smallish but then opens up, similar to Vaca Ha, with beautiful formations everywhere. There is a T soon after entrance with the left branch doing sharply deeper, through the halocline and into amazing saltwater passage known as Gateway. The right branch apparently continues for 1200 ft in the freshwater zone.
Salt water passage was amazing with smallish tunnels right in the middle of halicline that made shooting very challenging. The erosion of the cave showed exactly how it was formed in the first place. The camera ran out of juice as soon as buddy and I came out of salt zone and into the fresh (we shoot on the way back), so only 2 pictures of freshwater formations.
