The growing suburban landscape of Washington County is documented here during a period of significant expansion, as shown by the 1970 photorevisions overlaying the 1961 base map. Beaverton and Tigard emerge as major hubs, connected by the Southern Pacific and Oregon Electric Pacific rail lines. The map reveals the transition of agricultural land into residential communities like Raleigh Hills and Cedar Hills, while still preserving large social landmarks such as the Portland Golf Club and the Portland Hunt Club. Further south, the meandering Tualatin River flows through a landscape defined by industrial and community features, from the Cipole Grave Pit and various quarries to local institutions like St Marys Boys Home. Prominent natural landmarks like Bull Mountain and Sexton Mtn provide a vertical contrast to the developing flats and river valleys, offering researchers a clear view of the area's mid-century topography and infrastructure.
