where are the rainforests in Oregon

Washington Olympic Peninsula rainforest: look at a map and drive/hike up any of the rivers coming from the interior and you're in the rainforest. The Hoh, Sol Duc, Elwha, Dungeness, Bogachiel, Queets, Quinault. In the North Cascades as well these river: the Nooksack, Skagit, Sauk, Stillaguamish. Lots and lots of rain back in those hills and the water sheds for many of the cities in NW Washington. Nothing like this in the Oregon mountains.
