Thanks to Pacific Horticulture Magazine and Daniel Mount for this article

The Willamette Valley, SW Washington, Puget Sound outwash prairies, and southern B.C. are all connected (geologically and topographically). This pops out on a foggy day as seen from a weather satellite: note the light gray fogged-in valleys all the way from Oregon to Canada!
