About this map

Whitman National Forest dominates this high-elevation terrain in the Blue Mountains, where a complex network of forest development roads provides access to the headwaters of the region's major drainage systems. The La Grande Reservoir serves as a critical focal point in the southern portion of the map, fed by high-country streams like Beaver Cr and Beatty Cr. The local infrastructure is specifically geared toward water management, as evidenced by the La Grande Aqueduct tracing the contours of the landscape.

Prominent landforms like Elk Mtn and Beaver Ridge define the verticality of the area, providing a natural boundary for the numerous creek basins. These waterways, including Whiskey Cr and Jordan Cr, are part of a dense hydrological web that has supported timber and water interests for decades. The map also identifies specific natural water sources like Beaver Spring and Bucket Spring, which are essential markers for those navigating the backcountry.
