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.
The Beach (film) Controversy arose during the making of the film due to 20th Century Fox's bulldozing and landscaping of the natural beach setting of Ko Phi Phi Leh to make it more "paradise-like". The production altered some sand dunes and cleared some coconut trees and grass to widen the beach. Fox set aside a fund to reconstruct and return the beach to its natural state; however, lawsuits were filed by environmentalists who believed the damage to the ecosystem was permanent and restoration attempts had failed.[3] Following shooting of the film, there was a clear flat area at one end of the beach that was created artificially with an odd layout of trees which was never rectified, and the entire area remained damaged from the original state until the tsunami of 2004.
