With far more accurate GPS data processed by Ross Overstreet, King and I returned in Arcturus to dive these amazing pinnacles. Locating this site windward of Catalina was like geocaching at sea because nothing on the surface could tell us if we anchored in the right place. Only the dive itself could tell us if we got it right. And we did! Fields of purple hydrocoral and an ecosystem I never imagined could exist in California. My best dives in a long time! We even located the shallowest pinnacle at 50 ft and visited the E wall to 87 ft.
