1997 Map of Illahee Rock

USGS Topo · Published 1999

About this map

The North Fork Umpqua River carves through the center of this landscape, defining the topography of the Umpqua National Forest in the late 1990s. The small settlements of Illahee and Flats sit along the river's path, where the valley floor widens enough to accommodate habitation. This area is a critical node for forest infrastructure and power generation, anchored by the Soda Springs Power Plant and supported by the Marsters Bridge river crossing.
