About this map

Cascadia marks the northern edge of this high-elevation landscape, where the foothills transition into the Cascade Range. The topography is defined by the massive bulk of Swamp Mountain and the prominent Green Mtn Ridge to the south. This area, largely contained within the Willamette National Forest, is characterized by a dense network of drainages that feed the region's larger river systems.

A complex hydraulic pattern is evident in the many named creeks, such as Little Wiley Cr, Wolf Cr, and the uniquely named Flimflam Cr. The map details the headwaters of the South Fork Calapooia River, illustrating how the terrain's steep contours dictate the path of local waterways like Cul de Sac Cr and Boundary Cr. This 2017 survey serves as a modern record of the forest's hydrological and geological structure.
