Depth is medium-shallow. Substrate is mainly a gravel/sand/cobble mixture surrounding numerous large boulders. Red (1:34 seconds) and brown seaweed was abundant. Four species of browns were recorded and mainly consisted of the perennial seaweed Pterygophora californica (0:17-0:19seconds), Saccharina spp. (0:29, 1:21 seconds) and Pleurophycus gardneri (1:47 seconds). The pink growth on boulders is crustose coralline algae (1:44, 1:53 seconds). Green sea urchins (Strongylocentrotus droebachiensis) were still very abundant, especially in the last 10 meters of the transect (1:53-2:00 seconds).
