This is a well-known dive off the West side of Domville Island in the Sidney area. I'm not sure who Graham is, but I assume he's the diver who discovered/popularised this place. The wall is marked by a small reef maybe 200 meters offshore from Domville Island. This reef is exposed at most tides. I took my zodiac (May 31, 2009) to the beach on Domville across from the reef to zip up my drysuit before motoring to the reef and anchoring in the kelp. The current seemed pretty strong even though the current atlas showed about 3 hours with no current and the tide graph was fairly flat. I tied off my boat to a bunch of kelp just in case the anchor didn't hold and rolled into the water. Sure enough the current was strong, but I could just swim against it. The visibility was also pretty terrible (about 6 feet). I swam down the far side of the reef, which is where the wall is. I was a bit disappointed by the marine life. The rock was mostly bare and silty with the kind of marine life that you get in lower-current areas (mostly urchins, sea stars and california cucumbers). The bottom of the wall met sand at around 75 feet. There were a lot of sea pens here. I continued North along the wall and eventually the good part of the dive showed up. Here the wall was covered with those small, multicoloured tunicate colonies (I should look up their name one of these days), cemented tube worms, cup corals and plumose anemones. This part of the wall went down to about 90 feet deep. Visibility seemed better here (maybe 10 feet). I don't know if the water was actually clearer or if there was just less glare from the sun scattering off the particles. The wall reminded me of Ten Mile Point, but with less variety (hardly any sponge and no hydrocoral, etc.). I also didn't see as many fish here as at Ten Mile. I saw a few rockfish (copper, quillback, yellowtail) and a kelp greenling. I still think it's a pretty good dive. It must be much more impressive with better visibility. I was swimming against the current for most of the dive so I turned around and was swept back to where I started. Fortunately, the boat was still there.
