2020 Map of Henley Basin

About this map

The Snake River carves a deep path through this borderland, forming the natural boundary between Oregon and Idaho. On the western bank in Baker County, the terrain is defined by dramatic drainages like Billy Gulch and Ryan Gulch that descend toward the river. Access to this reach of the canyon is provided by the unpaved Snake River Rd, which follows the shoreline's contours. To the east, the landscape rises into the high country of the Henley Basin, a significant topographic depression drained by Henley Cr. This area is crisscrossed by remote service roads including Henley Basin Rd and Mineral Rd, reflecting the region's historical reliance on grazing and resource access. Small tributaries such as Bear Cr, Rock Cr, and Grouse Cr create a complex network of canyons that feed into the main river system.
