Breccia
In my lengthy Ancient History post below, I mentioned the soupy breccia that formed after the meteor impacted in the ancient ocean 350 million years ago. The last time I was down near Roundrock, I snapped this photo of some exposed breccia with the round rocks eroding from it.
The rock face here is about ten feet high, and I am standing perhaps five feet below its base. Note the sculpting of the breccia. That was done by waves in the ancient sea so very long ago. Beautiful!

the bluffs above our favorite walk along port townsend bay (an offshoot of puget sound) are maybe 80 feet tall. much of the part not covered by vegetation looks like this. owls and cliff swallows, and maybe more, enlarge the holes where rocks fall out to make nests. the tree with the eagle, pictured on our blog today, is at the top of the bluffs.

were you in town the day the meteor hit?

Alas, had I been around then, I think I would have been vaporized along with everything else. Some days I do feel as though I am 350 million years old though.
