About this map

The high-elevation terrain of Modoc National Forest dominates this northern California landscape, centered on the strategic transit point of Adin Pass. Numerous forest spurs and secondary roads, such as Stone Coal Road and Harris Spring Spur, carve through the complex topography of the Warner Mountains region. The map reveals a reliance on natural water sources in this arid environment, documenting a network of springs including Schaffer Spring, Rice Spring, and Hoskins Spring.

Distinctive geological features like The Cliffs and Round Valley define the southern portion of the sheet, while prominent peaks like Schaffer Mtn and Grouse Mountain overlook the drainage systems of Dutch Flat Cr and Rush Cr. The surveyor's documentation of numerous "flats"—such as Roney Flat and Rice Flat—indicates pockets of level ground utilized for grazing or transit amidst the surrounding canyons of Niles Canyon and Barber Canyon.
