I wanted to check out the reef indicated on underwater maps in the Pit area north of Twin Peaks. I had looked for it years ago with Devin MacKenzie but we found nothing down to 190'. This time Kevin and I went back with 15/55 (he used JJ CCR; I had a 21/35 stage for travel and deco) and found the reef (a field of large boulders) starting around 220' and dropping steeply to at least 260', where we spotted a crinoid. There was not a lot of encrusting life but there were a fair number of juvenile rockfish, ling, etc. We found the reef by heading North from the end of Twin Peaks, and following the 230' contour east.
