2024 Map of John Lewis Mountain

About this map

Dworshak Reservoir dominates the western edge of this Idaho landscape, where the North Fork Clearwater River winds through a complex network of steep drainages. The topography is defined by prominent elevations such as John Lewis Mtn and Bear Butte, alongside distinctive landforms like Griner Saddle and Lightning Points. Human activity is concentrated along a handful of specialized routes including Bog Island Rd and Silver Creek Rd, which provide access to the remote Big Island Airport. The map documents a dense hydraulic system of mountain streams, from the headwaters of Reeds Creek and Meadow Creek to smaller tributaries like Feary Creek and Canoe Creek, illustrating the drainage patterns that feed into the larger reservoir system.
