Cliffs of Coquina in the Matanzas River...bizzarrro!?! (audio ALERT! I have no idea what happened when I was using Google Earth!!)

Coquina is a shell limestone and a staple in colonial building from the Florida Keys all the way up into Coastal Virginia. St Augustine would not still be standing without it. We have outcrops of it on the Atlantic beaches but also in the old river bed bottoms. Finding the ancient quarry sites in the middle of river beds is sorta spooky, eh? Makes one aware of the massive terraforming amidst our riverbeds, worldwide.
I also must apologize, the audio went wanko and I don't know why, on and off. So hopefully the images are still interesting! Sorry for the goofiness and hope you enjoy!!!
