The Wallowa Mountains are a mountain range located in the Columbia Plateau of northeastern Oregon in the United States. The range runs approximately 40 miles (64 km) northwest to southeast in southwestern Wallowa County and eastern Union County between the Blue Mountains to the west and the Snake River to the east. The range is sometimes considered to be an eastern spur of the Blue Mountains, and it is known as the "Alps of Oregon". Much of the range is designated as the Eagle Cap Wilderness, part of the Wallowa–Whitman National Forest.
The Wallowa River is a tributary of the Grande Ronde River, approximately 55 miles (89 km) long, in northeastern Oregon in the United States. It drains a valley on the Columbia Plateau in the northeast corner of the state north of Wallowa Mountains.
The Hells Canyon Wilderness is a wilderness area in the western United States, in Idaho and Oregon. Created 48 years ago in 1975, the Wilderness is managed by both the U.S. Bureau of Land Management and the U.S. Forest Service and contains some of the most spectacular sections of the Snake River as it winds its way through Hells Canyon, North America's deepest river gorge and one of the deepest gorges on Earth. The Oregon Wilderness Act of 1984 added additional acreage and currently the area protects a total area of 217,927 acres (88,192 ha). It lies entirely within the Hells Canyon National Recreation Area except for a small 946-acre (383 ha) plot in southeastern Wallowa County, Oregon which is administered by the Bureau of Land Management. The area that is administered by the Forest Service consists of portions of the Wallowa, Nez Perce, Payette, and Whitman National Forests.
The Imnaha River is a 73.3-mile-long (118.0 km) tributary of the Snake River in the U.S. state of Oregon. Flowing generally east near the headwaters and then north through Wallowa County, the entire river is designated Wild and Scenic. It follows a geologic fault to the Snake River, and in addition to land in the Wallowa–Whitman National Forest and private land, its corridor includes parts of three special management areas: the Eagle Cap Wilderness, Hells Canyon National Recreation Area, and Hells Canyon Scenic Byway. The Imnaha flows by the unincorporated community of Imnaha, the only settlement along its course, and enters the Snake River roughly 4 miles (6 km) from the larger river's confluence with the Salmon River of Idaho and 192 miles (309 km) from its confluence with the Columbia River.
Eagle Cap Wilderness is a wilderness area located in the Wallowa Mountains of northeastern Oregon, within the Wallowa–Whitman National Forest. The wilderness was established in 1940. In 1964, it was included in the National Wilderness Preservation System. A boundary revision in 1972 added 73,000 acres (30,000 ha) and the Wilderness Act of 1964 added 66,100 acres (26,700 ha) resulting in a current total of 361,446 acres, making Eagle Cap by far Oregon's largest wilderness area.
The Blue Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the Pacific Northwest, mainly in the state of Oregon, with small areas over the state border in Idaho and southeastern Washington.
