The boulder and ledge complex near the washout held several large Wolf Eels. Fish life was otherwise dominated by Buffalo Sculpins; a few massive individuals could, at first glance, pass for stubby Lingcod.
A large kelp-brown Penpoint Gunnel had lost its grip in the ebb and was drifting accordion-fashion. We traveled together for a while until it collided with a strand of sugar kelp and took refuge there.

Very hazy but enjoyable dive on the wall - probably 4 large wolf eels in total. Lots of logs in the water!
