My fellow divers have pretty much got it. If you dive it in the winter, be EXCEEDINGLY careful!! The entry rocks ice-up like nobody's business and if the waves slam into the sheltered cove from the north there is great danger of being slammed into the rocks if you don't time it just right. I went in 2 times on some pretty rough surge and surf. I call it the "giant washing machine". The best thing to do is before entry, dump your BC's air and go in heavy, get beneath the surge and surf as quickly as possible, kicking out into the cove, surface and wait for your team with your back into the waves. Then upon regrouping, descend and drop over the north wall for calmer conditions and better viz. Both dives that were nightmarish going in, were 2 of my most beautiful dives for the wall diving.
