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.
Long Beach, California Long Beach lies in the southeastern corner of Los Angeles County and borders Orange County.[17] Downtown Long Beach is approximately 22 miles (35Â km) south of downtown Los Angeles, though the two cities share an official border for several miles.
