where does siesta key beach sand come from
Siesta Beach 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.[3] Even on the hottest days, the sand is so reflective that it feels cool underfoot. It's estimated that the sand on Siesta Beach and Crescent Beach on Siesta Key is millions of years old, having its origin in the Appalachians and flowing down the rivers from the mountains until it eventually was deposited on the shores of Siesta Key.
Glass Beach (Fort Bragg, California) Glass Beach is a beach in MacKerricher State Park near Fort Bragg, California, that is abundant in sea glass created from years of dumping garbage into an area of coastline near the northern part of the town.[1]
