Just in time for the latest meme/theme circulating in the geoblogosphere, here is a nice outcrop of columnar basalt. You'll need to click the pics for full size and clarity.
Flash Earth location and image... there's a nice paved pullout on the downhill side of the road for this one. I'm not sure if the pullout is there for the obvious geology or for the view, but the view has been overgrown by all the green biological stuff over the years.

These are just the recent ones; if more come up in the near future, I'll try to keep this updated for a few days. For example, I'm sure Dana got more photos... I didn't even get out of the car. And for more background on the interpretation of the Siletz River Volcanics, see my post on our first Marys Peak Stop. Dana has also posted some very nice photos from that stop.
