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…

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…
