About this map

Callahan serves as the primary named point of interest in this upland territory of Douglas County, where the landscape is defined by a dense network of watercourses and timber access routes. The terrain is dominated by prominent landforms such as Rattlesnake Ridge and Green Butte, while drainage flows through the Hubbard Creek and Mill Creek systems. A distinct shift in character occurs in the northeast at Coles Valley, where Coles Valley Creek winds toward Churchill Rapids.

Evidence of local land management and water control is visible through features like Grier Reservoir and Hawkins Lake. The map details a complex system of forestry and access roads, including Callahan Rd and numerous BLM routes, which trace the steep contours of Bear Ridge and Long Ridge. This 2023 survey provides a contemporary perspective on the geographic interface between the more developed valley floors and the high ridges that separate the various creek basins.
