Cascade Mountains in the context of "Pacific Northwest"

Blanca Lake is located in the Henry M. Jackson Wilderness Area in the Cascade Mountains of the U.S. state of Washington.

Blanca Lake sits in a basin surrounded by the peaks of Monte Cristo, Kyes, and Columbia. The lake is fed by the Columbia Glacier to the northwest and is drained by Troublesome Creek, a tributary of the North Fork Skykomish River. The glacier's cold, silt-filled melt water is what makes the lake a spectacular turquoise green color making this a prime example of a rock flour lake.

The Seattle metropolitan area is an urban conglomeration in the U.S. state of Washington that comprises Seattle, its surrounding satellites and suburbs. The United States Census Bureau defines the Seattle–Tacoma–Bellevue, WA metropolitan statistical area as the three most populous counties in the state: King, Pierce, and Snohomish. Seattle has the 15th largest metropolitan statistical area (MSA) in the United States with a population of 4,018,762 as of the 2020 census, over half of Washington's total population.

The area is considered part of the greater Puget Sound region, which largely overlaps with the Seattle Combined Statistical Area (CSA). The Seattle metropolitan area is home to a large tech industry and is the headquarters of several major companies, including Microsoft and Amazon. The area's geography is varied and includes the lowlands around Puget Sound and the Cascade Mountains; the highest peak in the metropolitan area is Mount Rainier, which has a summit elevation of 14,411 feet (4,392 m) and is one of the tallest mountains in the United States.

The Pasayten Wilderness is a 531,539 acres (215,106 ha) protected area located within Okanogan–Wenatchee National Forest and Mount Baker National Forest in Washington state, centered on the Three Forks (48°54′02″N 120°38′01″W / 48.900584°N 120.6336808°W / 48.900584; -120.6336808) of the Pasayten River, a tributary of the Similkameen River. Although part of the wilderness lies in Mount Baker-Snoqualmie National Forest, the largest section falls within the boundaries of Okanogan National Forest, which has responsibility for the wilderness's management. The wilderness is bordered by the Stephen Mather Wilderness to the west. The northern boundary of the wilderness is the Canada–US border. Across the border are Manning Provincial Park and Cathedral Provincial Park. The wilderness area is adjacent to the Ross Lake National Recreation Area to the west, and North Cascades National Park beyond that. The Pacific Crest National Scenic Trail has its northernmost section in this wilderness. The western part of the wilderness features dramatic views and peaks of the northern Washington Cascade Mountains while the eastern section is known for its grasslands and Alpine tundra. The tallest point in the Pasayten is Jack Mountain.

The Pasayten is traditional hunting territory of the Nlaka'pamux peoples of the Fraser Canyon and Nicola Country along with adjoining parts of the Cascade Range, although there are no Nlaka'pamux populations on the Washington side of the border.

Mount Baker Wilderness is a 119,989-acre (48,558 ha) wilderness area within the Mount Baker-Snoqualmie National Forest in the western Cascade Range of northern Washington state. Its eastern border is shared with the boundary of the Stephen Mather Wilderness and North Cascades National Park for a distance of 40 miles (65 kilometers). The wilderness extends from State Route 20 north to the Canada–US border. On the west, it is bounded by the foothills of the Puget Sound lowlands.

Almost entirely within Whatcom County, the wilderness lies on the western slopes of the Cascade Mountains. The three forks of the Nooksack River and the Baker River are the major drainages of the wilderness.

The Coquihalla River (originally locally /ˌkɒkɪˈhælə/ or more recently and popularly /ˌkoʊkɪˈhælə/) is a tributary of the Fraser River in the Cascade Mountains of the Canadian province of British Columbia. It originates in the Coquihalla Lakes and empties into the Fraser River at Hope.

The Coquihalla River forms the northern boundary of two portions of the Cascades, the Skagit Range and the Hozameen Range. The river flows through a deep, narrow valley, dropping 3,400 feet (1,000 m) in 33 miles (53 km), a tumultuous course that creates an incessant roar.
