Geo 730: July 11, Day 557: Stumped Again

Dana stopped by yesterday with her friend B, and we went over to the coast, where it was a blissful relief from the heat here. We mostly revisited stops I've previously covered, but we did hit one new place, Boiler Bay, north of Depoe Bay. It wasn't the greatest geology, but it was awfully pretty, and there were a couple exposures that were quite interesting. I'll get to them in this series eventually. We also went down to the beach at Seal Rock, and saw a *great* contact between CRB and Astoria or Yaquina Formation (some uncertainty what the unit is). Again, I'll get to it sometime.

In the meantime, back to the Sweet Home and Quartzville area. Above is the second petrified stump at the community museum. While you can't get a good look at the grain of the taller one, this one is much shorter, so you can see the broken end and the wood grain very well. The tephra plastered on to the outside is poorly sorted; it looks like this was rapidly buried in a lahar.
