From this viewpoint almost 500 feet above the water we can see an almost "top view" of the bay below us, back toward Otter Rock. The photo is poor, sorry, but the light was fading rapidly. Look closely and you can see flat platforms of wave cut terraces, with homes built on them. In the water we can just make out ring patterns of rocks which break the incoming waves. These are the erosional remnants of plutonic ring and radial dikes that formed around the vent of a coastal volcano. The vent would have been located inland about 700 feet. There did not seem to be any obvious remnants of a neck or vent on the upland slopes. The volcanic cone has long since eroded, and possibly been covered by other formations.
