Corals are marine invertebrates in the class Anthozoa of phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. The group includes the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.

Cali secret spots.Any guess what made these towers? hint.. snorkle..

These are the Trona Pinnacles located outside of Death Valley. They are made of CORAL.. yes, more or less, coral. They are composed of calcium carbonate made the remains of small creatures trying to reach up from the sea to catch some rays. The massive sea is now gone. One place in the world you won't need goggles to get a glimpse of a massive reef. Love sharing the strangest spots in the world.
