First, take a look at this straight looking shape jutting out over half a mile into the Adriatic Sea at Trave, Italy? It looks like a man made jetty with boats anchored on the leeward side. Well, it's not man made. It's a natural geological formation--a angled uplift of layers of ancient seabed that you can see in the second photo going straight op the mountain. The effects of vulcanism in Italy are amazing to see.
