This formation is called the pirate ship. And is really pretty in the early morning light. The tufa towers are caused by carbonated fresh water mixing with the calcified salt water and making limestone. The water is 2.5 saltier than the Pacific ocean and more Alkali. This made the water foam more easily and the boat left an interesting wake as we headed out to Paoha Island. The rocks on the north end of the island contain boiling springs and steam vents. Impressive up close and also a bit wiffy. The top of the cone also has steam vents dotted around here and there. Heading back across the glassy lake. The perfect day!
