Oct. 5, 1983 Take hot volcanic material, put it in contact with water, and you've got the mix for a phreatic eruption. More than three years later, after such events had long since ceased in the North Fork Toutle River valley, scientists freely walked the floors of pits created by these eruptions.
A high-angle aerial photo looks down into a wide, flat-floored pit with pale tan ground streaked in orange. Steep gray and white walls rise around it, with dark rocky debris spilling down one slope. A few tiny people stand near the middle of the floor. October 5, 1983. Lyn Topinka, USGS.

May 1990 | The Toutle Ten years after the eruption, KGW went to a stretch of the Toutle River called Maple Flat. Nearly a dozen houses stood in the settlement on May 18, 1980. All of them washed away. Further downstream, homes were still threatened by riverbank erosion. Tim Storrs reports.

Oct. 1, 1980 | Clearcut Station Much like before the eruption, when scientists tracked the bulge pushed out by intruding magma on the north face, scientists here were watching for a large influx of magma pushing through the remaining edifice of the mountain. 📷 Terry Leighley
Two people in olive-green coveralls stand on ashy gray ground littered with fallen trees and stumps, facing Mount St. Helens. One holds a sheet of paper, and the other has hands on hips. Yellow tripods stand beside them, one topped with an orange instrument, and cases and bags sit on the ground nearby. A white plume rises from the broken top into a deep blue sky. October 1, 1980.

Lots of folks felt that earthquake yesterday. Had it been stronger, there's a chance people might have fallen and gotten hurt. That's why we suggest people drop to the ground if possible -- an essential part of drop, cover and hold on.

This morning's "Today's Document" from the National Archives was a 1946 aerial photograph of our good friend Loowit. Since they're not on here, here's an annotated version of the image with some...okay, a good number of landmarks noted on screen — many of which are still here.
A black-and-white aerial photo looks straight down on Mount St. Helens before it erupted. Rough, ridged slopes fan out in every direction from a bright white patch of snow and ice near the center, with narrow strips of snow filling the gullies. White labels mark landmarks. The Pre-1980 Summit sits at the center with Shoestring Glacier just above it, and The Boot is to its left with Dogs Head higher up. East Dome and the Plains of Abraham are near the top. Warm Flows and Monitor Ridge are on the right. Windy Pass, Sugar Bowl, and Goat Rocks run down the left edge, and Floating Island Lava Flow and Toutle Canyon are at the bottom left. September 28, 1946. National Archives, Records of the Defense Intelligence Agency, modified with added labels.

1982 | Gophers and Plants Two years after Mount St. Helens erupted, researchers were surprised by what had survived. Pocket gophers had lived underground on stored roots and seeds. Weedy, root-sprouting plants were reclaiming blowdown. Peter Graves narrates this early look at the recovery.

May 18, 1980 | Yakima By mid-morning, ash from Mount St. Helens had turned the skies dark as night. First responders pulled on whatever protective gear they had on hand. From face masks to goggles, anything to keep the gritty, chalklike material out. 📸 Sherry Bockwinkel / Yakima Herald-Republic
Four police and fire personnel stand close together in the dark, caught by camera flash. Each wears goggles and a white cloth mask over the nose and mouth. Three wear brimmed helmets, and one wears a close-fitting hood. Ash flecks their heavy coats and collars. May 19, 1980. Sherry Bockwinkel, Yakima Herald-Republic.

A yellow border frames a photo of dense, pouch-like ash clouds resembling mammatus formations, filling the upper two-thirds, with a flowering pink/red tree and part of a house visible at the bottom. White text lists the issue's contents, headlined 'Mount St. Helens' with three article titles — 'Mountain with a Death Wish,' 'In the Path of Destruction,' and 'The Day the Sky Fell' — followed by unrelated features on Nebraska fossils, airplane design, Poland, and cockroaches.
