There are two mountains in Oregon commonly called Scott Mountain. The Scott Mountain further north, in the Willamette National Forest, is sometimes confused with and referred to as Olallie Mountain; while some records show these two summits in Lane County as the same, other records indicate differently. According to the Willamette National Forest website and Google Maps, these two summits, although within approx. 30 miles of the other, are clearly unique.. This Scott Mountain has its summit in Lane County, Oregon, in the United States. The mountain is in the Mount Washington Wilderness and the Willamette National Forest.
