About this map

Umatilla National Forest encompasses this high-elevation landscape, where a dense network of ridges and drainages defines the geography. High points like Thimbleberry Mtn and Huckleberry Mtn dominate the central terrain, while Goodman Ridge and McDonald Ridge extend across the northern reaches. The area is characterized by an intricate water system, including the S Fork Umatilla River and various named springs such as Bear Camp Spring and Dead-Horse Spring, which likely served as critical water sources for forest travelers and early sheep or cattle drives.

Evidence of human movement through the forest is preserved in the Huckleberry Mountain Trail, which traverses the southern slopes. This map provides a clear record of naming conventions tied to the landscape and local history, from the ominous Hellhole Cr to the distinctive formation at Gray Rock. Geographic landmarks like Pileup Saddle and Dusty Saddle indicate established crossing points through the steep topography of Umatilla County.
