1987 Map of Crescent Valley

Evidence of early 20th-century transportation remains visible through the Old Railroad Grade and the active Southern Pacific line traversing the northern edge. Small, isolated outposts such as Tenabo, Cortez, and Alpha anchor the map, serving as reminders of the region's mining and ranching heritage. From the high summit of Mount Lewis to the seasonal waters of Carico Lake, the survey documents a classic Basin and Range environment where water sources like Horse Creek and Pine Creek dictate the placement of human activity.
