Above (click to enlarge): Aerial view of Catalina's Isthmus - also known as "Two Harbors". Isthmus Harbor is nearest to the viewer in the photo, and Catalina Harbor, a favorite deep harbor for Spanish Explorers in the 1500's and 1600's is facing away from the viewer.
This walk through California's most amazing water wonderland, Catalina, is dedicated to David Blackford, El Segundo High Class of 1977 (of which I am also a member). Go Eagles!
