These photos are from March 26, 2010. Visibility was about 10-15 feet. Near the beginning of the wall (the end below the fence), there was a line of urchins leading off into the distance. While most of the bottom here was shells and small rocks, the urchins seemed to be following a narrow strip of larger rocks. This "avenue" of rocks almost looked like it was artificially placed. I followed it out to a low rocky reef covered with more urchins and giant barnacles. It seemed to end eventually about 100 feet deep. There wasn't much else living on it so I spent the rest of the dive back on the wall.
Although there were lots of bits floating around, visibility was about 20 feet today (April 25, 2010). There were also quite a few visiting divers in the water so it was nice to not have to charge around taking self-portraits if I wanted a diver in the picture.
