The Siletz River and its numerous tributaries dominate this high-elevation landscape along the border of Lincoln and Polk counties. This terrain is defined by dramatic peaks and ridges, including Diamond Peak, Green Mtn, and Fanno Peak, which stands as a prominent landmark on Fanno Ridge. The drainage network is particularly complex here, with the South Fork Siletz River and S Fork Siletz River carving through the mountains alongside smaller streams like Fourth of July Cr and Whiskey Cr.
