MSH80_st_helens_spirit_lake_before_may_18_1980.jpg
Before the devastating May 18, 1980 eruption, Mount St. Helens was considered to be one of the most beautiful and most frequently-climbed peaks in the Cascade Range. Spirit Lake was a vacation area offering hiking, camping, boating, and fishing.

MSH70_shoestring_glacier_southeast_side_09-70.jpg
Southeast side of Mount St. Helens, showing Shoestring Glacier. This pre-1980 view of Mount St. Helens shows the volcano's southeast flank and the headwaters of the Muddy River before the 18 May 1980 eruption. The broad forested area in the foreground is underlain by many layers of volcanic deposits, chiefly lahars and pyroclastic flows generated from past eruptions of Mount St. Helens.

MSH80_aerial_st_helens_summit_03-24-80_bw.jpg
Aerial view, Mount St. Helens' summit. Image taken from USGS Professional Paper 1250, with caption: "Aerial view of upper cone, looking west-southwest. Although seismic activity began under Mount St. Helens on March 20, this overflight showed no unusual features except numerous tracks of earthquake-triggered snow avalanches. No evidence of fracturing of summit area was detected during careful visual observations on the afternoon of March 24, 1980. On March 25, the first cracks were noted by Bud Kimball, Tacoma, Washington.".

Mount St. Helens' eruption, first crater. Aerial view on the afternoon of March 27 looking east, showing newly formed crater, swath of dark new ash mainly to the southeast of new crater, and east-west fault across middle of summit area, and an uplift or bulge on upper north flank of the volcano. Image is a portion of larger image.

MSH80_st_helens_summit_two_craters_03-30-80_bw.jpg
Mount St. Helens' summit after several small explosive eruptions. The smaller of the two pit craters was formed first on March 27. Subsequent eruptions opened the farther crater. The two craters subsequently merged. View looking west. Image from USGS Professional Paper 1250.

MSH80_two_tone_st_helens_with_rainier_03-30-80_bw.jpg
Aerial view of a two-tone Mount St. Helens with Mount Rainier in distance. View looking north-northeast. Ash covered snow is a result of wind direction, resulting in left portion of cone free of ash while the right portion is covered. Snowstorms later covered these ash layers, which in turn were covered by new ash. The result was many alternating layers of snow and ash. Image from USGS Professional Paper 1250.

MSH80_steam_blast_from_summit_04-06-80.jpg
Steam-blast eruption from summit crater of Mount St. Helens. Aerial view, April 6, looking southwest, showing a roiling, gray-brown, ash-laden cloud that envelops and almost completely hides an initial fingerlike ash column, and an upper white cloud formed by atmospheric condensation of water vapor in the convectively rising top of the eruptive column. Image and caption taken from Professional Paper 1250 and not scanned from original slide.

The smallest of five major volcanic peaks in Washington State was Mount St. Helens, with an elevation of 9,677 feet (2,950 meters) before the eruption of May 18, 1980. Another Cascade volcano, Mount Adams (12,286 feet [3,745 meters]), is in the distance. The view is from the west.

On March 20, 1980, after a quiet period of 123 years, earthquake activity once again began under Mount St. Helens volcano. Seven days later, on March 27, small phreatic (steam) explosions began. This view is from the northeast.

MSH80_st_helens_bulge_from_NE_04-13-80.jpg
A "bulge" developed on the north side of Mount St. Helens as magma pushed up within the peak. Angle and slope-distance measurements to the bulge indicated it was growing at a rate of up to five feet (1.5 meters) per day. By May 17, part of the volcano's north side had been pushed upwards and outwards over 450 feet (135 meters). The view is from the northeast.
