These are digital pictures I took during my 2011 trip to San Francisco. In a fit of nostalgia, we went to Treasure Island and walked around the base. Although there was residential housing at one end of the island, the majority of the naval school buildings were still there. It was sad, because the barracks (I lived in Cosson Hall) were new when I was there in the early 70s, but in 2011 they were boarded up and the inside was completely wrecked and covered with graffiti.
