Great for technical divers who want to go deep. At the base of the wall, the boulder-covered bottom slopes down as deep as you want to go. Not much life on the wall itself. Near the bottom of the wall there are some chimney sponges. Some have decorated warbonnets living inside. DON'T TOUCH! If you touch the sponges, they will break and die. These aren't normal "spongy" sponges, but fragile, slow-growing "glass" sponges. A diver who has been diving here a while says that there used to be one of the biggest Cloud sponges in the area here, but curious divers kept poking at it and it crumbled away. Be aware of where your fins are kicking.
