About this map

The John Day River carves a significant course through this portion of Grant County, serving as a primary corridor for early movement and settlement. Near the riverbanks, points like Stewarts Crossing and the Aldrich Grave indicate the human footprint on this high-elevation landscape, where cattle ranching and resource management defined the economy. The presence of the Communication Tower and various gravel pits suggests the transition toward modern infrastructure and road maintenance within the rugged interior.

Deep within the Malheur National Forest, the terrain rises sharply toward the Aldrich Mountains, punctuated by high-country features such as Pinchot Lake, Roosevelt Lake, and Stewart Lake. Named drainages like Schoolhouse Gulch and Scotty Creek reveal the historical importance of water access for both livestock and the small outposts like Stockdale. For researchers, the map provides a clear view of the complex topography leading to Chilkoot Pass and the summit of Aldrich Mountain.
