A couple of miles up the road from my last post, I saw these basalt columns protruding vertically upward. They were located on a different ridge. The forces driving the uplift were different than the ones from the first ridge. I ask why, what caused the difference? Did this ridge lift at a different time or were the forces just different from the ridge in the first post. My curiosity kills me. I think I need to do more research on how these “Yakima Folds” evolved.
