Marys Peak, the most notable in Oregon’s Coast Range, reaches 4,097 feet above sea level.

The Klamath Mountains are in the southwest corner of Oregon and include the Umpqua Mountains and the Siskiyou Mountains. Mt. Ashland marks the highest elevation in this region, reaching approximately 7,500 feet. Unlike other regions in Oregon, the Klamath Mountains have not been primarily formed by volcanism.

In Southeast Oregon, Steep-walled basins and fault-block mountain ranges define the Basin and Range region. At 9,738 feet and stretching for 50 miles, Steens Mountain dominates this region and is often confused for a mountain range.

Mount Hood

Oregon’s most notable mountain range, however, is the Cascade Range, which covers about 17 percent of the state and stretches for 260 miles. Known as the range that divides the state, in Oregon’s Cascade Range you’ll find more peaks over 9,000 feet than in nearby Washington and seven different national forests – the most notable being Mt. Hood National Forest. Comprised of mostly volcanic mountains (some still active), the Cascade Range is customarily divided into two physiographic sub-provinces, the Western Cascades and High Cascades.

The Western Cascades are considered a very old and eroded mountain range. Often referred to as the ‘old cascades,’ the Western Cascades are covered in vast forests containing -fir, true firs, and hemlock. Although the High Cascades tend to attract more visitors, the Western Cascades offer a variety of hiking trails and are best-known for a 220-mile scenic byway that offers incredible views of Mt. Jefferson, Mt. Washington, and Three Fingered Jack.

The High Cascades dominate Oregon’s skyline and are where you’ll find the state’s tallest peaks and six active volcanoes: Mt Hood (11240 ft), Mt. Jefferson (10,497 ft), South Sister (10,358 ft), North Sister (10,052 ft), Middle Sister (10,036 ft), and Mt. McLoughlin (9,495 ft). Mt. Hood, Mt. Jefferson, the Three Sisters, and Crater Lake (which was formed by the eruption of Mt. Mazama), are all considered to be the highlights of the High Cascades. However, other recognizable glaciated peaks include Three Fingered Jack (7,844 ft), Mount Washington (‎7,798 ft), and Mount Thielsen (9,184 ft).
