Under the Highway 101 bridge, at the southern end of the Depoe Bay metropolitan area, one can see the narrow neck of the channel into the eponymous bay. I can't tell, at the resolution of the photos I have, what form the basalt is taking here. I suspect it's predominantly breccia, perhaps with some isolated pillows, based on the patchy white spots. The latter are almost certainly composed of zeolites and/or calcite, which are signature accessory/secondary minerals with mafic to intermediate lavas in wet environments.
