About this map

Pine Mountain Observatory crowns the high ground in this 2011 survey of the high desert landscape east of the Cascades. The map details a transition from the broad Millican Valley in the north to the uplift of Pine Mountain, where a complex network of forest and development roads, including Nat For Dev Rd 2017 and Sand Springs Rd, provides access to the terrain.

Evidence of the region's volcanic and arid character is seen in features like the Lava Bed Rd and the seasonal path of the Dry River. Remote infrastructure is scattered throughout, from the Millican Airstrip near the northern boundary to Antelope Spring in the southeast. The survey highlights how the landscape is managed through various Forest Service routes that intersect at West Basin Canyon, revealing a working landscape defined by its geology and astronomical observation.
