There are numerious downed trees around the edges of this hole down to a plateau at about 35-40'. Viz down to this level was about 20'. Moving out towards the center, on the NE side, you will spot some rock cliffs going deeper. Poor visibility at that depth, and lack of drysuits prevented us from going deeper on the first dive. I would like to think that the poor viz was due to the thunder storms that passed through earlier that day. The water was very warm on the surface but quickly went to 47 degrees at depth. There were these little, white worms below the thermocline. They were about 1/2 to 1" long and theyt were wiggling all over the place. Above the thermocline nothing but fish were present.
