2020 Map of John Lewis Mountain

About this map

Dworshak Reservoir defines the western edge of this landscape, where the rising waters meet the steep drainage systems of the Clearwater region. The terrain is dominated by high points like John Lewis Mt and Bear Butte, with the land carved by a complex network of waterways including Big Cr, Evans Cr, and Reeds Cr. These drainages dictate the location of local infrastructure, such as Silver Creek Rd and Big Island Rd, which navigate the contours of the timbered slopes. Aviation access in this demanding environment is represented by the Big Island Airport located near the reservoir's banks. The map provides a clear look at the land division system across the 38th and 39th North Townships, showing the placement of ridges like Griner Saddle and Lightning Points that separate the various forks of the Silver and Big Creek systems.
