This divide between the Willamette River drainage and the Umpqua River drainage to the south is the highest elevation part of this birding trail. The hemlock, red-cedar and Douglas-fir forest with patches of alder, maple, and madrone is home to Ruffed and Sooty Grouse, Northern Goshawk, Spotted Owl, Pileated and Hairy Woodpeckers, Hammond’s and Olive-sided Flycatchers, Gray Jay, Hermit and Varied Thrush, Hermit, Wilson’s and MacGillivray’s Warblers, Western Tanager, and Red Crossbill. The crest of the divide at Snow Peak offers stunning views in all directions. Hike or bicycle along gravel side roads for access to more of the habitat, but be sure to watch for logging trucks. Note: This road can be closed due to snow in winter and early spring. Carry tire chains or traction tires and winter survival gear if you travel this route between November and May.
