Mount Hood, the nearest major volcanic peak in Oregon, is 60 miles (100 km) southeast of Mount St. Helens. Mount St. Helens is geologically young compared with the other major Cascade volcanoes. It formed only within the past 40,000 years, and the summit cone present before its 1980 eruption began rising about 2,200 years ago. [ 11 ]
The Mount St. Helens Visitor Center at Silver Lake, about 30 miles (48 km) west of Mount St. Helens and five miles (8 km) east of Interstate 5 (outside the monument), opened in 1987 by then-Vice President George H.W. Bush. The center was formerly operated by the U.S. Forest Service and has been operated by Washington State Parks since October 2007.
The east flank of Mount St. Helens is within the watershed of Muddy Creek. [5] During the 1980 eruption of Mount St. Helens, lahars (volcanically-induced mud and debris flows) swept through its channel. [6] About 135 miles (217 km) of stream channels around the volcano were affected by lahars. [6]
The Dome is a 5,720+ ft (1,740+ m) mountain summit located in Mount St. Helens National Volcanic Monument, in the Gifford Pinchot National Forest, in Skamania County of southwest Washington state. [3] It is situated in the Cascade Range, less than 2 mi (3.2 km) north of Spirit Lake, and 1.28 mi (2.06 km) northeast of Coldwater Peak.
Coldwater Peak is a 5,722 ft (1,740 m) mountain summit located in Mount St. Helens National Volcanic Monument, in the Gifford Pinchot National Forest, in Skamania County of southwest Washington state. [1]
[2] [4] It is located on the boundary shared by Mount St. Helens National Volcanic Monument and Gifford Pinchot National Forest. Castle Peak is part of the Cascade Range, and it is situated one mile (1.6 km) west of Castle Lake. Topographic relief is significant as the summit rises 2,000 feet (610 meters) above Castle Lake in one mile.
Mount St. Helens, once the fifth-tallest peak in Washington State, lost about 1,300 feet from its height of 9,677, according to the USGS. The highest part of the crater rim on the southwestern ...
Then, on May 18, 1980, the dramatic eruption of Mount St. Helens shattered the quiet and brought the world's attention to the range. Geologists were also concerned that the St. Helens eruption was a sign that long-dormant Cascade volcanoes might become active once more, as in the period from 1800 to 1857 when a total of eight erupted.
