Water was very brown/green from algae bloom (see photo).

  • Much more than the normal number of Dungeness and Mole crab carcasses and parts all the way along the mile. Note also the greenish foam, presumably the result of upwelling and possibly a cause of the crab die-off.

Lots of birds but few humans on this remote stretch of beach. Crab boat just offshore; large ship at anchor perhaps 10 miles offshore, possibly dumping ballast. There's a bird radar installation on...
  • Geo-Marine Inc. is setting up a bird radar station, probably to count birds after dark, when we humans can't see.
  • 3 immature and one adult Double-crested Cormorant
  • Brown Pelicans headed out to sea, showing how they tail-gate in flight.
  • Brown Pelicans headed north. Note black, gray and white on wings and body.
  • View of Sanderlings in dense group, showing how they're all on one leg, and eyes closed.
