Very interesting. That has always been one of my favorite places on LC to dive, and it's in my log book as "Ken Wagnon's Beach". I always go out from shore at the driveway which is on the north side of Ken Wagnon's house, then cruise from there up to Joy's Joy. Chris McCoy told me several years ago that DOE was saving that area for a new dive site some day, and I guess that day has now arrived. I haven't seen where they put the mooring ball yet, but would guess it's on the inner wall. The reef tops on the outside are fairly deep. But come to think of it, that driveway is right on the marine park boundary. From the description above, I guess the mooring ball must be straight out that driveway in about 40' of water.
