Mount Saint Helens.
Saint Helens definition by American Heritage Dictionary
A borough of northwest England east-northeast of Liverpool. It is an important center of glass manufacture. Population: 102,000.
A volcanic peak, 2,549 m (8,363 ft) high, of the Cascade Range in southwest Washington. Before its violent eruption on May 18, 1980, it was 2,949.7 m (9,671 ft) high. The eruption produced a smoke plume visible over much of western Washington and Oregon, set off fires and mud slides that killed at least 65 people, and covered a large area with a blanket of volcanic ash. Sporadic eruptions of lesser intensity have occurred since that time.
