About this map

Mutton Mountains define the high country of Wasco County in this 2020 topographic study, which reveals a complex network of forest and service roads threading through the high desert terrain. The map details a landscape where water is the primary architect of the geography, from the deep incision of Indian Head Canyon to the essential water sources like Mutton Mountain Spring, Eagle Springs, and Little Eagle Spring.

Evidence of the area's geological and logistical character is found in the varied creek systems, including Quartz Cr and Skookum Cr, which drain the flanks of prominent peaks like Shaniko Butte. The road network, primarily composed of numbered routes such as S-322 RD and S-320 RD, alongside the named Mutton Mtn Rd, illustrates how this high-altitude region is managed and accessed. The southern portion of the quadrangle descends toward Hellgate, marking a significant transition in the local topography.
