The Willamette River defines the southern boundary of this valley landscape, where the growing city of Newberg serves as a hub for the surrounding agricultural districts and hills. This survey, updated with revisions from the early 1980s, shows the transition from the riverbanks at French Prairie to the rising slopes of the Chehalem Mountains and Parrett Mountain. The presence of the Southern Pacific railroad line and the Pacific Highway West illustrates the region's importance as a transportation corridor connecting the fertile valley to larger markets.
