The Columbia River dominates this mid-century survey, dividing Oregon's Morrow County from Washington's Benton County. In this era, the river landscape is defined by the massive Blalock Island and the diverging North Channel and South Channel. Near the shoreline, the town of Boardman serves as a hub for both the Union Pacific railroad and local agricultural infrastructure.
