The range extends from the Willamette River east of Newberg northwest to the foothills of the Oregon Coast Range south of Forest Grove.  The highest peak in the Chehalem Mountain Range is Bald Peak, rising to 1629 ft , which is also the highest peak point within the Willamette Valley.

Cascade Range: The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California.  It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades.  The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains.  The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park.

Wind River Range: The Wind River Range (or "Winds" for short), is a mountain range of the Rocky Mountains in western Wyoming in the United States.  The range runs roughly NW-SE for approximately 100 miles (161 km).  The Continental Divide follows the crest of the range and includes Gannett Peak, which at 13,804 feet (4,207 m), is the highest peak in Wyoming.  There are more than 40 other named peaks in excess of 13,000 feet (3,962 m).  With the exception of the Grand Teton in the Teton Range, the next 19 highest peaks in Wyoming after Gannett are also in the Winds.  Two large National Forests including three wilderness areas encompass most of the mountain range.  Shoshone National Forest is on the eastern side of the continental divide while Bridger-Teton National Forest is on the west.  Both National Forests and the entire mountain range are an integral part of the Greater Yellowstone Ecosystem.  Portions of the range are also inside the Wind River Indian Reservation.
