Mount McLoughlin

From Oregon Hikers Field Guide

Mount McLoughlin from the summit of Pilot Rock (Greg Lief)


Mount McLoughlin is the highest peak in southern Oregon and is one of the most prominent landmarks in the region. It is a relatively young mountain that began forming about 700,000 years ago. The volcano last showed activity about 25,000 years ago, and it has been quiet since then. The mountain is in the southern portion of the extensive Sky Lakes Wilderness. Mount McLoughlin is the 6th highest mountain in the Oregon Cascades.

The summit of Mount McLoughlin can be reached via the five-mile Mt. McLoughlin Trail #3716, which crosses the Pacific Crest Trail in the wilderness. At the summit there still remains the foundation of what was a stone lookout shelter, constructed after the wood cabin of the first lookout was destroyed by fierce winds. You’ll see the cables and wires related to the lookouts. On a very clear day, views extend north all the way to South Sister in the north and Mount Shasta and Mount Lassen to the south.

The mountain is named after Dr. John McLoughlin, the Chief Factor of the Hudson's Bay Company at Vancouver who later moved to Oregon City.
