The Willamette River meanders through a complex network of sloughs and islands, including Hoacum Island and Norwood Island, defining the western boundary of this Willamette Valley survey. Further east, the landscape transitions into a grid of agricultural land and early rail infrastructure. Three major railroads, the Southern Pacific, Oregon Electric, and the Portland and San Francisco (Line), create a vertical transit corridor through the valley.
