Low tide at stonewall




Bob took some shots of me walking along the Stonewall reef with my flashlight. The minus 2.1 tide was at around 12:30 am so it was rather hard to see. The light in the top left corner is a boat heading into False Pass.
Because it was so dark, it was hard to get pictures that could show just how far the reef was exposed. There is another extremely low tide in April that will be during daylight hours.







As we approached Stonewall in the light of the full moon (this yellow light is from the boat), we flushed eleven bald eagles from near the top. The thoughts that flashed in our minds were: "Bats - big bats! wait - no bats live here." They were calling out and flying around in all directions. We'd noticed a population rise of eagles over the last few days and thought perhaps it had something to do with the low tides. A few weeks later and they are still here. So we think that it's more likely they are gathered for mating displays and to establish territories. They have been very active, flying in pairs and small groups, attacking individuals in exciting aerial displays. Yesterday I watched one fly backward, head and body angled down as in a dive, up and over a cliff, and moments later could hear the knock of talons locking from a pair of birds over the pass. It sounded like the horn-tangling of big game.










With lights we were able to find a good variety of little creatures-anemones, chitons (leather and lined), purple-ochre sea stars, a sunflower star, calcarious tube worms and spiny urchins. Not to mention thousands of mussels, barnacles, encrusting sponges and seaweeds (rockweed and ribbon kelp).
