Have you ever wondered what made the glistening white sand beaches of South Walton, FL? Well, millions of years ago, as the Appalachian Mountains eroded, quartz particles trickled down into the nearby streams. Then, these particles made their way into the Gulf of Mexico. Consequently, by the power of water, the quartz pieces broke down into smooth, sugar-like bits. Thus, this process created the crystalline white sands that make the water as blue as the sky. Pretty interesting, right?
