Mount McLoughlin is a steep-sided lava cone built on top of a composite volcano in the Cascade Range of southern Oregon and within the Sky Lakes Wilderness. It is one of the volcanic peaks in the Cascade Volcanic Arc. The mountain is north of Mount Shasta, south of Crater Lake, and west of Upper Klamath Lake. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. Mount McLoughlin has been known by a number of different names over the years, including Mount Pitt (after the Pit River), Big Butte, M'laiksini Yaina (Klamath Indians), Malsi (Takelma Indians), Mount Shasty (although this name was applied to Mount Shasta to the south by the 1841 Wilkes Expedition), and Snowy Butte.
The Pacific Crest Trail skirts the eastern and northern sides and also accesses the only trail to the summit. On a clear day, the Sky Lakes Wilderness, Crater Lake, the Rogue Valley, and Mount Shasta are visible from the summit.
Except for a short monograph written by Arthur B. Emmons in 1886, little was known about Mount McLoughlin's geology until the 1970s. Much of what is known today comes from LeRoy Maynard of the Center for Volcanology at the University of Oregon.
The 3-cubic-mile (13 km3) volcano went through three or four stages of development and stopped growing some time before the most recent period of glaciation about 25,000 years ago.
