#MountStHelens May 18, 1980, 8:32 AM. A colossal landslide. Magma & hot fluids explode, surge outward like a hot hurricane. Column rises, ash falls for miles. Snowpack melts, mudflows converge, lahars move downvalley. A 9-hr eruption. Everything is changed.

@getpseudoed I suggest you also check out this book (if you’re not already familiar with it). This is a fantastic resource.

@getpseudoed Last week protesters occupied & vandalized the Portland State University library. Originally they said the collections would be unharmed. They lied. The library will not reopen until fall while all the vandalism is cleaned up. This is not ok.

@pholser @KevinAprileCT This is my first choice for this category. A year or two after this album came out someone joked that they were going to rerelease the album as Boston’s Greatest Hits.

I ❤️ rock music.

@Scottmp123 It is. It’s an issues with museum panels on foam core. I like panels mounted or printed directly on a rigid substrate. When I still worked in museums our goal in designing exhibits was to make them “eighth-grader proof”. People want to touch things.

@getpseudoed I have two copies if you need more.

@AlaskaAir As a geologist, I can confirm the correct answer is the window seat. #MtHood

This large polished opal's inside, which has a botryoidal jasper formation constituting a unique inclusion, closely recalls nebulae in space

This is a macroscopic view of Normandy's beach sands. About 4% of it, is magnetic shrapnel that has been broken down over the decades into sand-sized chunks, coming from the fierce fighting on D-Day, 79 years ago #Today

Exciting news that the team on the current Joides Resolution cruise may have drilled through the Earth’s crust and reached the mantle. If confirmed, this is a huge first for geology. #ProjectMohole

[IODP at Texas A&M @JRSO_IODP]

More than 60 years after Project Mohole, @TheJR successfully drills and collects more than 1 km of mantle rock!
