About this map

Umatilla National Forest encompasses the deep drainages and rising spines of this Asotin County landscape, where water sources like Park Spring and Sheriff Spring provided vital points for early travelers and livestock. The map documents a complex system of ridges and gulches, including Smoothing Iron Ridge and Harlow Ridge, that dictated the path of historical routes such as the Asotin-Cloverland Road. These ridgelines separate significant canyons like Dark Canyon and Morris Canyon, illustrating the challenging geography of the northern Blue Mountains foothills.

Local landmarks such as Little Butte and Triple Ridge rise above a network of forest trails and secondary roads. The presence of seasonal labels like Cloverland (Snow) and Asotin Road 44 and 43 (Snow) highlights the high-elevation climate of this region. For the researcher, the map preserves the exact locations of remote springs like Arnold Spring and Vogan Spring, which were essential landmarks in the development of the area’s grazing and forest management history.
