2024 Map of Bonneville Dam

About this map

Stevenson and North Bonneville anchor this map of the Columbia River Gorge, where industrial infrastructure meets protected wilderness. The river serves as both a boundary and a corridor, featuring the Bonneville Lock and a network of islands including Bradford Island and Cascades Island. The landscape is dominated by steep terrain such as Greenleaf Peak and Rock Creek Butte, while the BNSF Railway tracks the northern bank. Local history is preserved in sites like Iman Cem and the Freddie Masterson Grave, providing specific touchpoints for genealogical research. The map also captures the confluence of major trail systems, including the Pacific Crest National Scenic Trl and Gorge Trl, which navigate the slopes between Gifford Pinchot National Forest and the Mark O Hatfield Wilderness.
