Coquina Rock

another beach type day. Took the ferry across and went to see the Coquina Rock again.
november 12 the rocks I wonder how much longer they will last. Lots of rock pieces were scattered on the beach..yes I took one..we are talking Pleistocene Era.
Between about 18,000 and 11,500 years ago the climate and environments of North America were changing rapidly. Temperatures were warming. Rainfall patterns were changing. The glaciers were melting. The seasonal difference in temperatures was increasing. WOW SOUNDS LIKE NOW, 2011.

Again another North Carolina Costal fact: this is called Coquina Rock and was formed during the Pleistocene Ice Age, approximately from 1.8 million years ago, until approximately 11,550 years ago. The end of the Pleistocene Era corresponds with the retreat of the last continental glacier, the sea level dropped, leaving the bar exposed to the air and weather. Rainwater dissolved the calcium carbonate from the shell and cemented the loose, shelly sediment into rock.
