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 many of those in 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 highest peak in the range is Mount Rainier in Washington at 14,411 feet (4,392 m).
The Columbia River Gorge is a canyon of the Columbia River in the Pacific Northwest of the United States. Up to 4,000 feet (1,200 m) deep, the canyon stretches for over eighty miles (130 km) as the river winds westward through the Cascade Range, forming the boundary between the state of Washington to the north and Oregon to the south. Extending roughly from the confluence of the Columbia with the Deschutes River in the east down to the eastern reaches of the Portland metropolitan area, the water gap furnishes the only navigable route through the Cascades and the only water connection between the Columbia Plateau and the Pacific Ocean. It is thus that the routes of Interstate 84, U.S. Route 30, Washington State Route 14, and railroad tracks on both sides run through the gorge.
Multnomah Falls is a waterfall located on Multnomah Creek in the Columbia River Gorge, east of Troutdale, between Corbett and Dodson, Oregon, United States. The waterfall is accessible from the Historic Columbia River Highway and Interstate 84. Spanning two tiers on basalt cliffs, it is the tallest waterfall in the state of Oregon at 620 ft (189 m) in height. The Multnomah Creek Bridge, built in 1914, crosses below the falls, and is listed on the National Register of Historic Places.
Mount Adams, known by some Native American tribes as Pahto or Klickitat, is an active stratovolcano in the Cascade Range. Although Adams has not erupted in more than 1,000 years, it is not considered extinct. It is the second-highest mountain in Washington, after Mount Rainier.
The Sandy River is a 56-mile (90 km) tributary of the Columbia River in northwestern Oregon in the United States. The Sandy joins the Columbia about 14 miles (23 km) upstream of Portland.
The Mount Hood National Forest is a U.S. National Forest in the U.S. state of Oregon, located 62 miles (100 km) east of the city of Portland and the northern Willamette River valley. The Forest extends south from the Columbia River Gorge across more than 60 miles (97 km) of forested mountains, lakes and streams to the Olallie Scenic Area, a high lake basin under the slopes of Mount Jefferson. The Forest includes and is named after Mount Hood, a stratovolcano and the highest mountain in the state.
Eagle Creek is a creek located mainly in Hood River County, Oregon, in the Columbia River Gorge, with its last roughly 0.5 miles (0.80 km) and mouth in Multnomah County. A tributary of the Columbia River, the creek flows for approximately 15 miles (24 km) from the Thrush Pond between Eagle Butte and Tanner Butte to its mouth near Bonneville Dam. The East Fork Eagle Creek is a major tributary that begins at Wahtum Lake and joins the main stem approximately 2/3 the way between the Thrush Pond and the Columbia River, separated by Indian Mountain.
The Bull Run River is a 21.9-mile (35.2 km) tributary of the Sandy River in the U.S. state of Oregon. Beginning at the lower end of Bull Run Lake in the Cascade Range, it flows generally west through the Bull Run Watershed Management Unit (BRWMU), a restricted area meant to protect the river and its tributaries from contamination. The river, impounded by two artificial storage reservoirs as well as the lake, is the primary source of drinking water for the city of Portland, Oregon.
Larch Mountain is an extinct volcano near Portland, Oregon. The name is misleading, as no western larch can be found there. It received that name when early lumbermen sold the noble fir wood as larch. The peak can be reached between May and November on paved Larch Mountain Road, 16 mi (26 km) east of Corbett, Oregon, although the road is closed during the winter and spring months. The road leading to Larch Mountain from the Historic Columbia River Highway is 14 miles long, which closed at milepost 10 from Nov. through late May or early June due to snow.
The Salmon River is a 33.5-mile (53.9 km) river in the Cascade Range in the U.S. state of Oregon that drains part of southwestern Mount Hood. The entire length of the river is a protected National Wild and Scenic River. Several portions are in protected wilderness. It is affluent to the Sandy River, a tributary of the Columbia River.
The Salmon–Huckleberry Wilderness is a wilderness area located on the southern side of Mount Hood in the northwestern Cascades of Oregon, in the United States. It lies within the Mount Hood National Forest and comprises 62,061 acres (25,115 ha) of land. The United States Congress designated the area Wilderness in 1984.
The Mark O. Hatfield Wilderness is a wilderness area located on the northern side of Mount Hood in the northwestern Cascades of the U.S. state of Oregon, near the Columbia River Gorge and within Mount Hood National Forest. Prior to Wilderness designation it was known as the Columbia Gorge Recreation Area.
Sheridan State Scenic Corridor is a state park in the Columbia River Gorge, west of Cascade Locks, Oregon. The 11-acre (4.5 ha) property, containing an old-growth forest, is located on the south side of Interstate 84 at approximately milepoint 42.5, and was not accessible by motor vehicle since I-84 was built in 1960. However, with the opening of the Eagle Creek-Cascade Locks segment of the Historic Columbia River Highway State Trail in 1998, it has become easily accessible by foot or bicycle. The park is on a triangular lot, surrounded by I-84 and the Mount Hood National Forest.
Timberline Trail is a hiking trail circling Mount Hood in the U.S. state of Oregon. It is mostly in wilderness but also goes near Timberline Lodge, Cloud Cap Inn, and Mount Hood Meadows ski area.
The Muddy River is a stream, about 29 miles (47 km) long, southeast of Mount St. Helens in the U.S. state of Washington. The Muddy River flows south–southeast and joins the Lewis River just above the Swift Reservoir. The Lewis River flows west and is a tributary to the Columbia River. The east flank of Mount St. Helens is within the watershed of Muddy Creek.
Mount Defiance is a peak near the Columbia River Gorge in the US state of Oregon. It rises to an elevation of 5,010 feet (1,527 m) in the Mount Hood National Forest in Hood River County, Oregon. The northern and western flanks of the mountain are in the Mark O. Hatfield Wilderness. The route up the mountain is often considered one of the hardest climbs in the Gorge; the trail gains 5,000 feet (1,500 m) in 6 miles (9.7 km) from the Starvation Creek Trailhead.
The Eagle Creek Fire was a destructive wildfire in the Columbia River Gorge, largely in the U.S. state of Oregon, with smaller spot-fires in Washington. The fire was started on September 2, 2017, by a 15-year-old boy igniting fireworks during a burn ban. The fire burned 50,000 acres, and burned for three months, before being declared completely contained. As late as May 29, 2018, it was still found smoldering in some areas.
Tanner Creek is a creek located in the Columbia River Gorge in Multnomah County, Oregon, United States, that is a tributary of the Columbia River.
Tanner Butte, officially Tanner Creek Butte, is a peak on the boundary between Hood River and Multnomah counties in Oregon, on the edge of the Columbia River Gorge. Its 4,478 feet (1,365 m) elevation makes it the highest point in the western Gorge. Tanner Butte is the high point on Tanner Ridge, a north-south ridge separating the Tanner and Eagle Creek drainages from each other. It is located in a remote area of the Mark O. Hatfield Wilderness, a wilderness area within the Mount Hood National Forest, on the boundary of the Bull Run Watershed.
The McCully Basin is a geologic structural basin in the northern boundary of Eagle Cap Wilderness in northeast Oregon. The basin is the topographic drainage of McCully Creek. Several Alpine Huts and campsite are located throughout the McCully Basin, which are used as a base camp in the winter for telemark skiing.
