Green Ridge dominates the western half of this landscape within the Cascade Range on the border of Deschutes and Jefferson counties. This 2014 survey captures a terrain defined by dramatic elevation changes, where high volcanic plateaus drop sharply into the Akawa Gulch and the distinctive topographic break known as The Gap. The map documents a complex network of forest roads and trails, such as the B-1 Logging Road and the Allingham Cutoff, which trace the historical and modern timber economy of the Deschutes National Forest. Water sources are vital landmarks in this high-altitude environment, including Bear Spring located near the northern boundary. The detailed contour lines reveal the volcanic geology of the region, from the slopes of Garrison Butte to the prominence of Little Akawa Butte, providing a clear record of the area's natural drainage and ridgelines.
