About this map

The Malheur National Forest dominates this high-altitude landscape in Grant County, defined by a complex network of springs and seasonal drainages. Within this protected wilderness, the North Fork Malheur Wild and Scenic River carves through the southwestern corner, while the headwaters of the Little Malheur River emerge to the northeast. The terrain is characterized by a series of high prairies and ridges, including Flag Prairie and the prominent Rattlesnake Ridge.

Resource-rich locations such as Bear Creek Meadow and Lost Dog Flat suggest a landscape historically important for seasonal grazing or wildlife management. Water remains the primary feature of this map, with dozens of named sources like Seven D Bar Spring, Alarm Clock Spring, and McKenzie Spring providing vital hydration points across the dry, elevated plateau. These features, along with landmarks like Bingham Point and Prairie Hill, provide essential navigational data for this remote section of eastern Oregon.
