About this map

Black Mountain Lookout stands as a prominent sentinel over this high-elevation landscape in Bonner County, Idaho. The terrain is defined by a series of significant peaks and ridges that dictate the drainage patterns for numerous waterways. South of Black Mountain, the geography funnels into notable transitions like Twentymile Pass and Kelly Pass, which served as critical navigation points through the high country.

A complex network of Forest Service and county roads, including Twentymile Creek Rd and Twentymile Peak Rd, provides access to the interior of these mountains. The hydrography of the region is exceptionally detailed, showing the headwaters of Twentymile Creek, Contrary Creek, and North Fork Grouse Creek. This 2011 survey documents the established access routes and topographical landmarks such as Twentymile Peak and Jay Peak before subsequent natural or human-led changes to the backcountry infrastructure.
