About this map

The Imnaha River carves a deep path through this corner of northeast Oregon, serving as the primary corridor for the small settlement of Imnaha. At the end of the twentieth century, this area remained largely defined by its dramatic elevation changes and the protected boundaries of the Wallowa National Forest. A Gaging Station and a small Cem are situated near the town center, while a Trailer Park provides local infrastructure alongside the river.

Extending eastward, the landscape transitions into the Hells Canyon National Recreation Area, where significant landforms like Grizzly Ridge and Dead Horse Ridge dominate the horizon. Connectivity is limited to routes like the Hat Point Road, which climbs toward the Fivemile Viewpoint and Hat Point, offering expansive views over the canyon system. The map documents numerous family-named canyons and basins, such as Adams Canyon and Maxwell Basin, reflecting the legacy of early ranching and land use in this isolated terrain.
