Rhododendron Ridge forms the high spine of this portion of the Mt Hood National Forest, dividing the complex drainages that feed into the Clackamas River and Collawash River. The 1997 revision of this landscape reveals a terrain defined by high-elevation meadows and industrial resource extraction. Named clearings like Jim Meadow, Rhododendron Meadow, and Eds Meadow dot the high country, while a series of gravel pits and quarries, including the Squirrel Quarry and Lowe Creek Pit, trace the network of forest roads. The presence of Graham Pass and Mount Lowe highlights the physical challenges of navigating this timber and watershed region. In the southern reaches, the isolated Round Lake sits near the border of Clackamas and Marion counties, providing a clear marker for those tracing land boundaries and drainage patterns in the northern Cascades.
