2017 Map of Glenoma

About this map

Glenoma occupies the southern valley floor along the northern edge of Riffe Lake, where the landscape transitions from the developed road networks of Lewis County into the steep drainages of the Snoqualmie National Forest. This 2017 study illustrates the complex hydrology of the region, featuring the confluence of multiple tributaries including Rainey Cr, Johnson Cr, and Steffen Cr as they flow toward the lake. The northern half is dominated by the upper reaches of the Tilton River system, with the E Fork Tilton River and W Fork Tilton River carving through the terrain near high-elevation points like Fern Gap. Extensive forest service and logging infrastructure, such as the Champion Haul Rd and various DNR routes, reveal the ongoing industrial character of these mountainsides, while isolated water bodies like McKinley Lake and Davis Lake highlight the area's natural geography.
