The Clackamas River and Sandy River define the industrial and transit corridors of this region during the early twentieth century. This survey, conducted by R.B. Marshall and his team, illustrates a landscape transitioning from pioneer homesteads to established townships linked by the Portland Railway Light & Power Company. The Cazadero Line and Oregon Water Power & Railway Company tracks provide the essential infrastructure for movement between Gresham and Estacada.
