About this map

Swamp Mtn and the Green Mtn Ridge dominate this portion of the Cascade Range within the Willamette National Forest. The landscape is defined by a dense network of mountain streams and forestry infrastructure, particularly the Natl Forest Develop Road 200 which traverses the central slopes. These drainage systems, including Little Wiley Cr and Wiley Cr, show a classic Pacific Northwest timberland pattern where complex ridgelines dictate the movement of both water and access roads.

In the southern reaches of the quadrangle, the headwaters of the N Fork Calapooia River emerge, joined by local tributaries like Potts Cr and the descriptively named Cul de Sac Cr. This 2020 survey documents the modern state of these public lands, illustrating how historical township and range boundaries—such as t14s r3e and t15s r4e—continue to organize the management of these high-elevation forests and their numerous creeks, from Wolf Cr to Flimflam Cr.
