![]() Two small towns, Glenwood and Trout Lake, are located in valleys less than 15 miles from the summit, Glenwood on the southeast quarter and Trout Lake on the southwest quarter. BIA 285 is known to be extremely rough and often suitable only for trucks or high-clearance vehicles. Access to the Mount Adams Recreation Area is by way of FR 82, which becomes BIA 285 at the Yakama reservation boundary. Almost all other roads are gravel or dirt, with varying degrees of maintenance. The main access roads, FR 23, FR 82, FR 80, and FR 21, are paved for part of their length. From either highway, travelers have to use Forest Service roads to get closer to the mountain. Highway 141 comes within 13 miles of Adams as it follows the White Salmon River valley up from the Columbia River to the small town of Trout Lake. Highway 12 passes about 25 miles to the north of Adams through the Cascades. Only two major highways pass close to it. Mount Adams is the second-most isolated, in terms of access, stratovolcano in Washington Glacier Peak is the most isolated. The Cispus and Lewis rivers have been impounded with dams farther downstream for flood control and power generation purposes. The Klickitat and White Salmon rivers are nearly completely free flowing, with only small barriers to aid irrigation (White Salmon) and erosion control (Klickitat). Streams on all sides, at some point in their courses, provide essential irrigation water for farming and ranching. Streams on the east side all flow to the Klickitat River. To the south, the White Salmon River has its source on the lower flanks of the west side of Adams and gains additional flows from streams along the southwest side of the mountain. The streams on the north and west portions of Adams feed the Cispus River, which joins the Cowlitz River near Riffe Lake, and the Lewis River. The many streams that emanate from the glaciers and from springs at its base flow into two more major river systems, the Cispus River and the Klickitat River. Meadows at Mount Adams WildernessĪdams is the source of the headwaters for two major rivers, the Lewis River and White Salmon River. Its large size is reflected in its 18 miles (29 km)-diameter base, which has a prominent north–south trending axis. Because of the way it developed, it is the largest stratovolcano in Washington and second-largest in the Cascades, behind only Mount Shasta. ![]() It is the second-highest mountain in Washington and third-highest in the Cascade Range. Standing at 12,281 feet (3,743 m), Adams towers about 9,800 feet (3,000 m) over the surrounding countryside. The current cone was built during the most recent major eruptive period 40,000–10,000 years ago. The whole mountain has been completely eroded by glaciers to an elevation of 8,200 feet (2,500 m) twice during its lifetime. Īdams is one of the long-lived volcanoes in the Cascade Range, with minor activity beginning 900,000 years ago and major cone building activity beginning 520,000 years ago. It is farther east than all the rest of Washington's volcanoes except Glacier Peak. While many of the volcanic peaks in Oregon are located on the Cascade Crest, Adams is the only active volcano in Washington to be so. The remaining area is within the Mount Adams Recreation Area of the Yakama Indian Reservation. Between half and two thirds of Adams is within the Mount Adams Wilderness of the Gifford Pinchot National Forest. The nearest major cities are Yakima, 50 miles (80 km) to the northeast, and the Portland metropolitan area, 60 miles (97 km) to the southwest. It is 30 miles (48 km) north of the Columbia River and 55 miles (89 km) north of Mount Hood in Oregon. Helens and about 50 miles (80 km) south of Mount Rainier. Mount Adams stands 37 miles (60 km) east of Mount St. Geography General Mount Adams from Wasco County, Oregon The Pacific Crest Trail traverses the western flank of the mountain. Its nearly flat summit was formed as a result of cone-building eruptions from separated vents. Īdams' asymmetrical and broad body rises 1.5 miles (2.4 km) above the Cascade crest. The eastern side of the mountain is designated as part of the territory of the Yakama Nation. The Mount Adams Wilderness consists of the upper and western part of the volcano's cone. Īdams, named for President John Adams, is a member of the Cascade Volcanic Arc, and is one of the arc's largest volcanoes, located in a remote wilderness approximately 34 miles (55 km) east of Mount St. It is the second-highest mountain in Washington, after Mount Rainier. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. Mount Adams, known by some Native American tribes as Pahto or Klickitat, is a potentially active stratovolcano in the Cascade Range. Yakama Nation / Skamania County, Washington, U.S.
