After finding an Earthcache up in Spokane, I was pleased to see one (of several)a little closer to home. This one is in a neighborhood in San Pedro, only a few blocks up the street from the harbor, where I occasionally go to sample fish. Not a real wonderful neighborhood, but a rarity in that the geology is exposed to view; normally placed like this would be covered up by iceplant or a retaining wall or something. In this case, one layer of ancient seabottom cuts across another, older and tilted at an angle. There are all kinds of fossils here; part of getting credit for this one was emailing in what made the holes in the sediments at the contact. Hint: there were fossils of them spread throughout these sediments.

There are some of them in this picture; click through to see notes.
These were much smaller holes nearer to the curb. There were made by much smaller, living critters - digger wasps! It was cloudy today though, so they weren't very active.
