2020 Map of Anderson Mountain

About this map

Anderson Mtn and Riddle Mtn define this high-altitude landscape in eastern Oregon, where seasonal drainages and isolated springs provided essential water for range management. The map reveals a network of natural catchments and naming conventions that speak to the region's ranching heritage, including Buck Pasture and the expansive Orejana Flat. Water sources like Louie Hughes Spring and Upper Paul Creek Spring are critical markers in this arid environment, while the presence of Three Lakes suggests unique hydrologic depressions atop the ridges. Access is limited to the remote Virginia Valley Rd and Anderson Valley Rd, which traverse the high ground between Anderson Valley and the surrounding peaks like Little Riddle Mtn. This document serves as a detailed record of the drainage patterns for Buster Cr and Paul Cr as they existed in the early twenty-first century.
