Sand can be a solid, a liquid or even, when wind blown, like a gas. This sand is fairly unique in that it is not made up of quartz grains or other hard rocks, but are shells of concentric layers of calcium carbonate
that has precipitated around a nucleus or central core. They are found in many locations around the world, but generally on the beaches of the Great Salt Lake in Utah. From the wind and the waves, there are many unusual formations.
