Last week friends and I traveled down the 17 South and I-95 to the St. Augustine area of Florida. I particularly enjoy these beaches because of the unusual rock formations found here. Specifically Coquina rock is a type of sedimentary rock (limestone) formed by deposits of mineral or organic ocean floor particles that merge into wonderful shapes and textures. They also create many tidal pools which are fascinating to explore. These images are from Marineland Beach and also a little further north at Matanzas Inlet.
