About this map

Coles Valley and the small settlement of Callahan anchor this 2014 survey of Douglas County terrain, where the topography is defined by high ridges and a dense network of creek drainages. The landscape transitions from the broader valley floor in the northeast near Churchill Rapids on the Umpqua River to the high elevations of Rattlesnake Ridge and Green Butte. Water management and natural catchment are evident through features like the Grier Reservoir, Lost Lake, and Hawkins Lake, which are tucked into the drainages of Hubbard Cr and Elgarose Cr.

A complex network of timber and access roads, including Callahan Rd and numerous Bureau of Land Management routes like BLM-25-7-29.0, suggests a landscape shaped by forestry and land management. The map details the transition from the Coles Valley Cr bottomlands to the steep divides of Bear Ridge and Long Ridge, providing a clear record of the intersection between these rural homesteading areas and the timbered uplands of the Oregon Coast Range.
