Wells et al. 2009"...folding in the embayment is driven by the clockwise rotation of Oregon about a pole near the OR-WA-ID border, compressing Washington against slow-moving Canada. The folds fan westward from this pole of rotation, and shortening increases to the west to about 7.1 mm/yr between Astoria and Penticton, BC. Shortening across the YFB is about 3 mm/yr and decreases eastward to the Idaho border." Wells, Ray E.; Blakely, Richard J.; Sherrod, Brian L.; Weaver, Craig S.
