Middle Santiam Wilderness Air Quality Report Wilderness ID: 216 Wilderness Name: Middle Santiam Wilderness Middle Santiam Wilderness Air Quality Report National Forest: Willamette National Forest State: OR Counties: Linn General Location: Central Oregon Cascade Range Acres: 8,900 Thursday, May 17, 2012 Page 1 of 4 Middle Santiam Wilderness Air Quality Report Wilderness ID: 216 Wilderness Name: Middle Santiam Wilderness Wilderness Categories Information Specific to this Wilderness Year Established 1984 Establishment Notes Oregon Wilderness Act of 1984 Designation Clean Air Act Class 2 Administrative Willamette National Forest Unique Landscape Features Mature old-growth trees shadow virtually all of this Wilderness, with Douglas fir, western red cedar, and western hemlock at lower elevations and true firs higher up. Some of the trees, estimated to be 450 years old, tower to more than 200 feet. Gently sloping, benchy terrain in the lower country starts at about 1,600 feet and rises to steep slopes, ridges, and peaks that reach 5,022 feet above sea level. The most prominent geological feature is 4,965-foot Chimney Peak, a lava plug in the northwestern portion. The Middle Santiam River flows through the area, slowing into quiet pools with mossy banks. Both the river and Donaca Lake teem with native fish, including chinook salmon during spawning season. Not far to the south lies Menagerie Wilderness. Four seldom-hiked trails provide access routes to the area: McQuade Creek (5.2 miles); Chimney Peak (12.7 miles); and Gordan Peak (6.1 miles), and Swamp Peak (6.1 miles).
