Last Autumn I was talking to a few divers from the Marker Buoy Club and they mentioned that there was a deep wall on the south side of the island that started at 130 ft. They mentioned that the deep wall wasn't connected to the wall that folks typically dive but could be reached by going straight out from the southern shore access point.
Has anybody ever done the deep wall? If so, what's it like and is worth spending the HE to go visit?
