The Clackamas River carves a deep valley through this landscape, marking a boundary between the emerging suburban developments of Gresham and the rural agricultural tracts of Damascus. In the early 1960s, this region was a mosaic of active industries and institutional growth, evidenced by the Hardscrabble Quarry and numerous gravel pits along the river banks near Barton. Transportation is defined by the Portland Traction Co rail line and the transition of older thoroughfares like Foster Road and Sunnyside Road into modern arterials.
