About this map

Maryhill sits prominently on the north bank of the Columbia River, marking a key crossing point where the Sam Hill Memorial Bridge spans the water to Biggs Junction in Oregon. This 2017 survey captures the modern landscape of the gorge, where the river widens into Lake Celilo. The terrain is defined by deep incisions like Frank Fulton Canyon and Hartley Canyon, which cut through the high plateaus of the Columbia Hills.

Tracing the transportation networks reveals the importance of the river corridor, with the Biggs Rufus Hwy and various rural routes such as Maryhill Hwy and Fulton Canyon Rd following the natural contours of the land. Smaller settlements like Thornberry are located south of the main river passage, while landmarks such as Biggs Arch and Bobs Point offer specific navigational reference points along the water's edge and the rugged basalt cliffs of the valley.
