They exist up and down the eastern seaboard. The entire region is the product of these three orogenies. And yes, since they were thrust at an angle, sometimes the PreC basement is preserved between, but they were layered above it in series.
I think Acadian is the accepted term in the literature.

"A boy has fed a fish too much? We will come at once!"
(I realize this is a pretty deep cut, but super relevant in my family)
I would only disagree with that 150 number! CAMP volcanism initiated at 201 Ma, including in the Hartford basin. But yeah, much later, unrelated to former orogenies except in the vaguest Wilson cycle sense.
We usually call the middle one the Acadian? At least around here!
It all basically looks like that, from all three orogenies. You just find sections that preserve distinct events in different locations, depending on which accreted block you are standing on and when it was metamorphosed and deformed. The region is basically a series of imbricated thrust sheets.
I suppose your name makes this pretty obvious if I was paying attention
lol
I wish I could read this for the first time again.
The thing politicians never, ever seem to remember is that preparation and accurate monitoring and forecasting for natural hazards is _ridiculously_cheap_ compared to cleaning up a disaster after it happens. Don't cut USGS hazards funding; mitigation pays for itself many, many times over!
Devastating: Hampshire College is permanently closing following the Fall 2026 Semester. A beautiful institution & community that has done so much for so many. My child is a current Hampshire senior. Hampshire's approach to education is so unique, humane, & exciting—I've seen it first hand. Tragic
Goodness, absolutely, no need to read anymore. That's fabrication of information and a basic scientific ethics violation. Do not publish and everything the authors submit should be suspect from now on.
I'm just going to look at this for a few minutes
You know, if you don't want something to happen, you can just not do it.
That was unfamiliar to me, too, but I'm not an expert on whether underwater steam explosions generate light. That's pretty specific knowledge!
Looks pretty real to me! This looks like a snippet from some tv show from a few years ago? I'm not familiar with the show, though.
those horrible we like tha moon guys. i’m really dating myself with this one
my whole feed today
whole lotta Moon up in here
It says I'm... both?? But I think I am neither, just mildly eccentric! And organized.
lol

A sign on the fence of a graveyard. It reads "No use of geiger counters on church property."
This sign raises many questions, which probably should be answered by the sign but aren't
You need to do it for phonolitic laccoliths! A bigger challenge
Same. This was a legitimately bad idea.
I don't miss all that much from Nebraska these days, but I do miss the abundant and [not quite as good as in Vietnam but still] very good pho.
The logic, insofar as there is any, goes like this: the war has crashed the global oil market so hard that the administration needs the enemy’s oil to keep gasoline prices from eating the midterms. They are unsanctioning the people they’re bombing because the bombing is working too well at the thing they didn’t want it to do. The sanctions were necessary to stop Iran funding the war, but the war made the sanctions too effective, so the sanctions had to be lifted to fund the war effort against the country that no longer needs sanctions because the oil revenues that sanctions were preventing are now required to prevent the economic damage caused by preventing those revenues, which is itself a consequence of the military campaign designed to make the sanctions unnecessary by making Iran the kind of country that doesn’t need sanctioning, which it would be, if the sanctions hadn’t been lifted to pay for making it that.
Speed read this paragraph and I thought I had a stroke.
How can this go on for another 3 years?
Nice rooster tails
Just curious before passing this along to someone: Are you at all interested in interdisciplinary scholars with backgrounds in applied computer and data science, who collaborate in earth sciences? Or only earth system sciences more strictly?
