The Mount St. Helens major eruption of May 18, 1980 remains the deadliest and most economically destructive volcanic event in U.S. history. Fifty-seven people were killed; 200 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche,…

Stampede Pass (elevation 3,672 feet (1,119 m)) is a mountain pass in the northwest United States, through the Cascade Range in Washington. Southeast of Seattle and east of Tacoma, its importance to transportation lies almost entirely with railroading, as no paved roads cross it. It is approximately twelve…

Cathedral Rock is an intrusive andesite volcanic complex. The Alpine Lakes Wilderness features some of the most rugged topography in the Cascade Range with craggy peaks and ridges, deep glacial valleys, and granite walls spotted with over 700 mountain lakes. Geological events occurring many years ago created…

The Mount St. Helens major eruption of May 18, 1980, is currently the most economically destructive volcanic event in U.S. history. 57 people were killed and 200 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (298 km) of highway were destroyed. A massive debris avalanche, triggered by a…

Despite its elevation of 10,541 feet (3,213 m), Glacier Peak is a small stratovolcano. Its relatively high summit is a consequence of its location atop a high ridge, but its volcanic portion extends only 1,600–3,200 feet (500–1,000 m) above the underlying ridge. Another Cascade Arc volcano with similar…

The mountain is home to diverse ecological zones, ranging from dense lower-elevation forests dominated by Douglas fir and western hemlock on its western slopes to drier ponderosa pine forests on its eastern slopes. These ecosystems support a rich array of flora and fauna, including large mammals like Roosevelt…

Lake River, a "slow, flat slough of the Columbia River", loses only 1 foot (30 cm) in elevation over its entire 11-mile (18 km) course. It flows north, roughly parallel to the Columbia until curving slightly northwest to join it. At times, tidal fluctuations and high flows along the Columbia cause Lake River…

Mount Stuart is more notable for its local relief than for its absolute elevation. For example, the south face rises 5,000 feet (1,500 m) in just 2 horizontal miles (3.2 km). The northeast and northwest sides of the mountain exhibit similar steep relief. Due to its location away from higher peaks, Mount Stuart…
