About this map

Callahan serves as a primary geographic anchor in this section of Douglas County, situated amid a complex network of timber and access roads that crisscross the high ridges. The landscape is defined by its significant relief, featuring Rattlesnake Ridge in the north and Bear Ridge further south. Water management and natural drainage are central to the area's character, evidenced by Grier Reservoir and the headwaters of numerous creeks including Hubbard Cr and Mill Cr.

To the northeast, Coles Valley provides a distinct break in the terrain, where Coles Valley Cr flows toward the larger drainage systems. Small bodies of water like Lost Lake and Hawkins Lake are tucked into the drainages of Cedar Cr and Hubbard Cr, highlighting the importance of these upland water sources. The extensive network of Bureau of Land Management routes, such as BLM RD 25-8-19, illustrates the modern logistical framework used to navigate the heavily forested terrain between Green Butte and Long Ridge.
