Lockwood over at the Interzone has recently noticed that there’s a columnar basalt theme going on in the geoblogosphere. So, to keep the ball rolling I thought I’d throw in one from central Oregon. This one is from outside the town of Kimberly, OR. I took it while on a field studies trip to the John Day Formation. If I’m remembering correctly this outcrop is part of the Picture Gorge basalt flow which is about 15 million years old.
