Ocean newest Rock

This is an original painting on canvas in acrylic. Alcatraz is one of my favorite California landmarks. I don't know if it stems from my childhood? The best 6th grade field trip I ever had was newest a trip to Alcatraz. We got our own tour guild and from what I remember a pretty awesome tour. Or it may just be the shear mystique of the little island that sits in the middle of the bay?
