About this map

Malheur National Forest encompasses this high-elevation landscape in Grant County, defined by a complex network of seasonal drainages and named meadows. The terrain is characterized by broad plateau-like features such as Five Hundred Flat and Grasshopper Flat, interspersed with prominent landmarks like Sand Mtn. A significant concentration of water sources highlights the area's importance for local land use, including The Potholes, Mud Spring, and Last Cabin Spring.

The hydrography of the region is dominated by the headwaters of numerous creeks, including the branching forks of Scotty Cr—divided into north, south, east, and little branches—and Officer Cr. These waterways carve through the forest towards Gilbert Ridge and Wymer Meadow. The map provides a contemporary view of these natural resources, documenting a remote section of Oregon where the forest management and natural topography remain primary features.
