Index card: Oblique aerial view looking into crater at dome that developed after the June 12, 1980 eruption. Note water in lake(s?) around its base. Skamania County, Washington. June 19, 1980. (Photo by Austin Post, USGS/Glaciology).

Aerial view of glaciated topography in the La Sal Mountains, Note large moraine in center of photograph, numerous cirques and a rock glacier in center of lower left quadrant, Grand and San Juan Counties, Utah. n,d.

Aerial view of crater rim following the May 18, 1980 eruption. Arrows above the far rim indicate exposed cross sections (left to right) of Forsyth, Nelson, Ape, and Shoestring Glaciers. The horizontal arrow on the near slope indicates typical rills and channels through ash deposits into Talus Glacier (note crevasse further down the glacier). Dark (wet) streaks to the left indicate the ash covered Toutle Glacier. Photo 8059-115 by Austin Post. Skamania County, Washington. July 24, 1980. Published as figure 7 in U.S. Geological Survey Circular 850-D. 1981.

Aerial view of Mount St. Helens from the northeast before the 1980 eruptive activity. Dashed line marks boundary of area removed by the May 18, 1980 blast. Photo 67L7-14 by Austin Post. Skamania County, Washington. September 18, 1967. Published as figure 4 in U.S. Geological Survey Circular 850-D. 1981.

Album caption: Sherman Glacier showing conditions before the earthquake; compare with photo no. 239 (ake00239). Cordova district, Cook Inlet region, Alaska. August 26, 1963. (Photo by A. Post). Published as Figure 7 in U.S. Geological Survey. Professional Paper 544-B. 1967.

Index card: A closer oblique aerial view of the east arm of Spirit Lake. Note the trees washed from the hillsides. Blast material displaced Spirit Lake water upward onto hills - the water then picked up the logs and flowed back into the lake on top of the blast materials. Skamania County, Washington. June 4, 1980. (Photo by Austin Post, USGS/Glaciology).

Index card: Eruption activity began on March 24, 1980 with a series of earthquakes. On March 27, 1980 steam and ash eruptions occurred. Two craters appeared on the peak which eventually came together forming one large crater. Running across the peak of the volcano in this oblique aerial view one can see the large crack that developed in the ice. In the right foreground is a massive bulge of material moving out as a result of pressure from within the volcano. Skamania County, Washington. March 30, 1980. (Photo by Austin Post, USGS/Glaciology).

Aerial view of Mount St. Helens from the northeast following the May 18, 1980 eruption. All remaining snow and glacier ice has been covered by ash and other volcanic materials, but the tongue of Forsyth Glacier is clearly discernible below and to the right of Dogs Head. Timberline road and parking areas, deeply buried under ash and debris, are outlined Photo 8059-227 by Austin Post. Skamania County, Washington. July 24, 1980. Published as figure 6 in U.S. Geological Survey Circular 850-D. 1981.

Index card: Oblique aerial view of the eruption of May 18, 1980 which sent volcanic ash, steam, water, and debris to a height of 60,000 feet. The mountain lost 1300 feet of altitude and about 2/3-cubic mile of material. Note the material streaming downward from the center of the plume and the formation and movement of pyroclastic flows down the left flank of the volcano. Skamania County, Washington. May 18, 1980. (Photo by Austin Post, USGS/Glaciology).

Typed caption on back of photograph: Mt. Baker, Washington, steaming. View west-northwest into Sherman Crater, Mt. Baker, Washington, showing major fumaroles (steam areas) and deposits of fumarole dust a) on the snow and ice in the carter. Central ice pit and warm lake (b), and enlarged former warm lake (c), are visible among steam plumes. Meltwater from the crater flows toward viewer through the east breach (d), and passes beneath Boulder Galcier (lower right edge of photograph) to reach upper Boulder Creek (not shown). Sherman Peak is marked "e" and Lahar Lookout "f". USGS photo by Austin Post, July 3,1975. No index card.

Index card: Looking south from timberline at the bulge. Immediately preceding the eruption of May 18, 1980 the bulge was growing at a rate of five feet per day. Helicopter at right. Skamania County, Washington. April 13, 1980. (Photo by Austin Post, USGS/Glaciology).

Index card: On March 27, 1980, observers saw Mount St. Helens erupt for the first time in 123 years. The eruption, which was preceded by a loud "boom," left a single crater, 200 to 250 feet across, in the snow and ice that capped the volcano's cone. The snow around the crater was coated with volcanic ash, a material that was to become all too familiar to many residents of the Northwest. The arial view here is from the north. Skamania County, Washington. March 27, 1980. (Photo by Austin Post). Published as Figure 10 (photos and captions reversed in publication) in U.S. Geological Survey. Professional Paper 1949. 1982.
