About this map

The Malheur National Forest dominates this landscape on the border of Grant and Harney counties, where the South Fork John Day Wild and Scenic River carves through the northern terrain. High-elevation peaks such as Alsup Mtn and Donivan Mtn define the topography, while lower-lying areas like Sunflower Flat and Sawtooth Meadows offer distinct clearings within the timbered reaches. The map reveals a complex network of springs and drainage systems, including Alsup Spring, Chris Borg Spring, and Crystal Spring, which feed into various creeks like Bear Cr and Rock Cr.

Water management and natural meadow systems characterize the land use here, evident in features like Rickman Reservoir, Divide Reservoir, and Spring Valley meadow. The southern portion includes the open expanse of Yellowjacket Field and Sage Hen Flat, which contrast with the more elevation-heavy northern ridges. Traces of early accessibility are visible along Co HWY 68 and the numerous named springs that once supported the cattle and forest operations in this part of Oregon.
