1974 Map of The Dalles North

About this map

The Columbia River serves as the focal point of this mid-1970s survey, marking the state boundary between Oregon and Washington. This reach of the river includes the distinctive Rowena Gap and Crates Point, with the water level regulated at the Bonneville Normal Pool Elevation 72. Transport and industry define the corridor, where the Union Pacific and Burlington Northern railroads parallel the banks. To the north, the terrain rises into the Columbia Hills, characterized by numerous drainages like Dillacort Canyon and Knight Canyon. The settlement of The Dalles is visible at the southern edge, supported by local infrastructure including the Chenoweth Sch and The Dalles Municipal Airport. Smaller communities such as Murdock and Smithville sit on the Washington side, while Mayer State Park provides recreation along the Oregon shore.
