15 sty 2024 · Where most beaches’ sand is made of pulverized coral, the quartz sand on Siesta Beach (just a hop, skip, and a jump from our hamlet on Turtle Beach) is actually an ancient product of the Appalachian mountains, and part of the sediments deposited on our shores after millions of years of down-flowing Appalachian river activity.
As the quartz made its journey, it was shaped and refined by natural forces, transforming from rough, rugged rock into the fine, delicate grains that now make up Siesta Beach. The process of erosion smoothed out the quartz, making it incredibly soft to the touch.
Siesta Beach (sometimes known as Siesta Key Beach) is a beach located on Siesta Key in the U.S. state of Florida. Unlike beaches elsewhere that are made up mostly of pulverized coral, Siesta Beach's sand is 99% quartz, most of which comes from the Appalachian Mountains. [1]
