About this map

Deschutes National Forest encompasses a landscape defined by volcanic activity and unique geological formations. Central to this area is the Newberry Volcano, whose historical eruptions created the eponymous Lava Cast Forest. This feature preserved the shapes of ancient trees encased in lava, forming a distinct environment that includes Hoffman Island. The topography is characterized by numerous volcanic peaks, or buttes, such as Ikt Butte, Mokst Butte, and Sugar Pine Butte.

Transport through this high-altitude region is limited to seasonal routes like the Newberry #80 (Snow) road. The southern portion of the map rises into the Paulina Mountains, featuring landmarks like Shoulder Butte and Kawak Butte. The arrangement of these features illustrates the complex eruptive history of the Newberry caldera's flanks, where cinder cones like Pine Cone Butte and Lockit Butte punctuate the forest canopy.
