About this map

The Snake River carves a deep, winding path through the borderlands of Oregon and Idaho, dominated here by the expansive Brownlee Reservoir. This 1980s topography highlights the massive scale of the Brownlee Dam, a central fixture that transformed the drainage patterns of the Hells Canyon region. The map captures the complex shoreline and steep canyon walls, where named features like Ferry Canyon and Black Canyon hint at the historical travel corridors and natural barriers of the Snake River gorge.

Small upland settlements and geographical markers provide context for local history, including the community of Wildhorse near the river and Heath tucked into the southeastern drainage. Remote mountain landmarks such as Officer Butte and Round Mountain overlook a network of backcountry routes, most notably the Board Grade. These details document the infrastructure and remote landscape of Baker, Adams, and Washington Counties during the late 20th century.
