Upper Preston: I-90 at MP 24.9
Among the places of Washington, Upper Preston stands out for its position on Interstate 90 in the forested foothills of the Cascade Range. This small unincorporated community lies in King County, east of Seattle, where the interstate forms a major east–west route across Washington and onward through the United States. Dense woodland lines the road corridor, placing Upper Preston in the transition between the Puget Sound lowlands and mountain country. Nearby Preston developed as a coal-mining settlement; that industrial past remains part of the area's local identity. The locality is defined by transport links, broad roadway infrastructure and the wooded terrain of the western Cascades.

Washington’s terrain runs from Pacific coastal lowlands in the west to the dry Columbia Plateau in the east, with the Cascade Range creating a marked climatic divide. Central Washington lies on the plateau side of the Cascades, where the Columbia River has cut broad valleys and irrigation supports orchards and vineyards. The state also includes Puget Sound, the intricate marine inlet around Seattle, and the volcanic cone of Mount Rainier. Seattle’s Space Needle, built for the 1962 World’s Fair, remains one of its most recognisable landmarks. Move on to other webcams in the region to compare landscapes and settings around Washington.

The Atlantic, Pacific and Gulf coasts define much of the United States — their ports, fisheries and trade routes have long tied the country’s economy to the wider world. Between them, the Rocky Mountains, Great Plains and Mississippi River basin form sharply different regions, from high western ranges to broad agricultural heartlands. Cities carry much of the national story: New York’s Statue of Liberty, a gift from France dedicated in 1886, remains an enduring symbol, while Washington, DC concentrates major federal institutions. Indigenous nations have shaped these lands for millennia, and their living cultures remain essential to the country’s identity.
