In this autumn photo the slow-flowing Tualatin carries hundreds of newly fallen Oregon ash (Fraxinus latifolia) downstream.
The Tualatin River begins in the Coast Range west of Portland, Oregon and meanders through a partly rural, increasingly urban valley until it joins the Willamette River near West Linn, a few miles upstream from Portland.
This picture was taken from the Shamberg Bridge on Roy Rogers Road, just north of Sherwood, Oregon in the Tualatin National Wildlife Refuge. Since the time when I took this photo, this road has been straightened and converted to a high use, high speed arterial. In the interest of safety, I recommend not using it for a photo platform today.
