2024 Map of Henley Basin

About this map

Henley Basin serves as a prominent landform within this corridor where the Snake River marks the high-elevation boundary between Idaho and Oregon. The landscape is defined by the steep drainage systems of the Brownlee Reservoir, including Morgan Creek, Rock Creek, and Perkins Creek, which cut through the complex topography of Washington County and Baker County. Cultural footprints are concentrated along the primary transit corridors, notably Snake River Rd and Mineral Rd, which provide access to the remote interior. Genealogists and local historians can locate the Hibbard Creek Cem positioned near the northern bend of the river, a rare named historical marker in a region dominated by sharp ridges and deep gulches like Billy Gulch and Ryan Gulch. The map illustrates the intersection of state lines and township boundaries, such as t13n r7w, against a backdrop of complex riparian and upland environments.
