Bates and Austin Junction serve as the primary human outposts in this 1951 survey of the Blue Mountains, where the extractive industries of the early 20th century meet the management of the Umatilla National Forest and Whitman National Forest. The landscape is heavily marked by gold and copper mining history, with numerous named sites such as the Ben Harrison Mine, Standard Mine, and Copperopolis Mine scattered across the high ridges. These operations were supported by complex water management systems like the Placer Ditch, essential for hydraulic mining in this terrain.
