About this map

Newberry Crater dominates this volcanic landscape, containing the prominent waters of East Lake and a series of dramatic geological formations within the Deschutes National Forest. The map documents the mid-20th-century intersection of recreation and industry, showing numerous campsites like Cinder Hill Campground alongside extraction sites including a Pumice Mine and various Borrow Pits.

Scientific interest in the area's thermal properties is evidenced by a Geothermal Test Well near the southwestern shore of the lake. The topography is defined by glass and ash, from the massive Big Obsidian Flow and Obsidian Cliff to the Central Pumice Cone rising from the lakebed. Volcanic features extend southward across the plateau, marked by several prominent buttes such as The Dome, Sand Butte, and Topso Butte, terminating near the distinct Surveyors Lava Flow at the southern boundary.
