The Tualatin Valley serves as the backdrop for this detailed topographical record of suburban development and agricultural transition in Washington County. Centered on the city of Beaverton, the landscape is defined by the elevation of Cooper Mountain and Sexton Mountain to the west, while the eastern edge blends into the Portland metropolitan area. Water systems like the Tualatin River, Fanno Creek, and Beaverton Creek create the drainage patterns that shaped early settlement and modern road networks. For those researching family history, the map includes several significant burial sites, including Patton Cemetery, Crescent Grove Cemetery, and Saint Anthony's Cemetery. Aviation enthusiasts will find small-scale infrastructure such as the Flying K Ranch Airport and Meyer Riverside Airpark, illustrating the area's mix of residential density and remaining open spaces.
