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,…

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…

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…

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…

Adams is one of the long-lived volcanoes in the Cascade Range, with minor activity beginning 900,000 years ago and major cone building activity beginning 520,000 years ago. The whole mountain has been completely eroded by glaciers to an elevation of 8,200 feet (2,500 m) twice during its lifetime. The current…
