March 1984 Dome-building continues. Hot rockfalls tumble down inside the crater, bright enough to turn the steam pink in this postcard long exposure spot. Down below, the pumice plain sits in silence.

To mark the arrival of a new eBay delivery I hope to share in the next few days, check out how HARD this hat goes. Go right now and get it.

Happy #FieldworkFriday! Some days our commute is a little more complicated than others. 4:30am - Leave Seattle 8:00am - Arrive at Mt St Helens staging area 8:30am - Helicopter leaves landing zone 8:40am - Helicopter lands at East Dome 8:45am - PNSN Field Crew begins maintenance on station EDM

Taken sometime in 1980—USGS caption notes: 'Mount St. Helens has a different charm today.' Well, yeah, when you've got a lenticular cloud doing that over your crater, you're bound to have *some* charm.

February 1983 Accompanying USGS volcanologist Don Swanson on Harry's Ridge today is Olaf, a postdoctoral scientist with the Survey. As Swanson looks through a theodolite toward Mount St. Helens, Olaf also watches the mountain—while nursing a can of Budweiser.

They make a nice addition to your living space and, get this, also a nice conversation starter if you want to talk about your historical volcanic social media accounts.

You may recall the story of the Davises, who were caught in the eruption in their pickup truck with their friend Al, miles north of the mountain. Here is a photo of their pickup in the devastated area, taken after May 18, 1980. The red trim is the only color in an awfully lifeless image.

@mountsthelens1980.bsky.social I keep forgetting to show you this meme I found in the wild:

We were watching a documentary on Mt. St. Helens tonight. I grew up in the PNW, and that's one of my clearest early memories. Mostly how dark it was, and wearing masks.

Co-star of the comedy sendup...er, serious disaster film "St. Helens" (1981)!

Its main sources are oral histories about Spirit Lake and Mount St. Helens, collected by the Oregon Historical Society from immediately after the eruption through 1981. Guess what? You can access them on the OHS's website.

Diving into Spirit Lake People, the mid-80s book of vignettes of life before the eruption. This 10-year-old miner’s nephew in 1924 shows what’s old slang is new slang, folks. Time is a flat circle.

Old school #DataViz? In a way. This WA Geological Survey plate map shows the time of first ashfall from Mount St. Helens on May 18, 1980. Isochron lines show the ash cloud’s eastward push across the Pacific Northwest, stretching into the morning hours of Monday, May 19.

The same exhibit had this drawing she made in Dec 1980

New from me @sfgate.com Last week, the Mount Rainier National Park website said it was getting rid of timed-entry reservations at the park in 2026. Several news outlets reported on it. Then NPS quietly changed the site to say no decision has been made yet. www.sfgate.com/national-par...

Late 1980s Let's take an aerial tour around Mount St. Helens less than 10 years after the May 18, 1980 eruption. From the log-covered waters of Spirit Lake to the devastated forests beyond, the return of life was underway, though sometimes hidden from the naked eye.

[Fourth Wall Break] As of January 29, 2026, we have officially reached 1,000 followers! This account was originally founded over a year ago to count down to the Golden Girls premiere in January 2025 (1985), and ever since, it continued into 1986, and I never expected it to get this huge.

Today marks the anniversary of the 1700 Magnitude 9 Cascadia Subduction Zone earthquake, reminding us to be prepared for strong shaking in the PNW. URMs are particularly vulnerable, but retrofitting can mitigate the risk. #FixTheBricks www.youtube.com/watch?v=C5wa...

Speculative fiction author Ursula Le Guin's self-portrait of her view of a pre-eruption Mount St. Helens, done before the mid-70s. Pretty cool.

SEAHAWKS ARE GOING TO SUPER BOWL LX!!!! Seattle Seahawks beat the LA Rams, 31 - 27! Hopefully you got to follow along and catch each incredible play of this nail-biting game in real time, but if not then find the whole-game archive at: pnsn.org/data-researc...

We're ready for you, 12s! The PNSN's field staff revisited Lumen Field this week to ensure our stations were functioning correctly so we can monitor all of the fan generated energy from today's Seahawks game vs the Rams. Make sure to follow our live seismogram during the game at seahawks.pnsn.org!

Looks like we've got a budding geologist in the works!

May 19, 1980 Woodland, Washington Roadside spectators peer through binoculars to see for themselves the now-truncated Mount St. Helens. The volcano continues to emit lazy ash clouds eastward from the mile-wide horseshoe crater. Meanwhile, t-shirt vendors are capitalizing on the eruption.

Tephra fallout in Volcano Village during yesterday’s Episode 41 eruption of #Kilauea.

Jan. 11, 1981 Despite new lava growing Mount St. Helens' dome, those on the mountain's west side aren't afraid. A small village of "20th-century pioneers" 14 mi. away, residents of St. Helens are doing just fine. Gary Carey says the volcano makes living there "more exciting...more adventure."

Anyway, here's Bill and Flo at Harmony Falls Lodge in 1977. Hope they had a great time. Looks like they're enjoying it.

in which two diverse accounts I follow, @everylot-usps.bsky.social and @mountsthelens1980.bsky.social, meet and shake hands

As I'm preparing to be covered in snow and more ice here on the East Coast, this seems nice at Kilauea. Put your hands up to the screen and warm up.

Happy #FieldworkFriday and happy #BlueFriday! We brought the 12s Flag up to station EDM on the side of Mt St Helens this week! It was a blue bird day up there with just enough wind to get the flag moving which made for perfect working conditions. Go Hawks!

@simonoxfphys.com is definitely up there. For geology content, GeoGirl. I love Nick's videos but they are LONG...I appreciate Simon Clark's brevity.

This series is soooooo gooood.

Looking at some old Forest Service photos. Here's the Visitors Information Center at Spirit Lake, circa 1970. It was here that Ranger Sharon Burchard felt the M4.1 earthquake on March 20, 1980, that indicated something was up at the mountain.

Mount St. Helens, May 23, 1980. Newly fallen snow on the slopes of the steaming volcano helps hide the scars left by the violence that rocked the peak five days earlier. The mountain simmers. 📸 @wadnr.bsky.social

This feels like yesterday.

We are all Cow

Vibes.

Join us on Wednesday evening at @MOHAI for a special event about the 2001 Nisqually earthquake. PNSN Director Harold Tobin and other excellent panelists will speak about how we can be prepared for the next one. Let's #FixTheBricks!
