Cave Pool
Detailed Description
A pool in the Caverns of Sonora. This cave, like many others, was formed by water combining with carbon dioxide to create a weak carbonic acid. This acid then dissolved the limestone to carve out chambers. The dissolved calcium from the limestone then combined with the carbon dioxide to create calcium carbonate, either in the form of calcite or aragonite, which was deposited along the surface of the cave to create the speleothems, or cave formations.
