2011 Map of South Ice Cave

About this map

The cinder pits of Deschutes County anchor this high-desert landscape, reflecting the region's industrial and geologic history. Industrial activity at the South Ice Cave Cinder Pit and Lava Crossing Cinder Pit stands in contrast to the recreational access provided at the South Lava Trailhead. This 2011 survey reveals an intricate grid of forest access routes, primarily defined by thoroughfares like Natl Forest Develop Road 18 Rd and Natl Forest Develop Road 22 Rd. These roads facilitate movement through the volcanic terrain near Lava Pass, connecting remote industrial sites with the few natural water features like Pine Lake at the southern edge. The map provides a detailed look at the National Forest road system used by loggers, miners, and outdoorsmen in the early 21st century.
