Okay I was totally wrong about how fast mountains form
I used to think mountain building was this super slow, steady process over millions of years. But I was reading a paper from the University of Utah last week about the Himalayas, and it said some of the big uplift events can happen in bursts over just a few thousand years. That's basically overnight in geologic time. It matters because it changes how we think about erosion and climate patterns tied to those rapid changes. I feel like a lot of people still have the old 'slow and steady' idea stuck in their heads. Has anyone else seen newer research on this kind of pulsed uplift in other ranges?
Honestly that Utah paper is super interesting, but the wording can trip people up. Tbh those "bursts" over a few thousand years are still incredibly slow by any human measure. It's more like the process isn't a smooth line, but has faster and slower chapters. The old "slow and steady" idea is mostly right for the whole picture, it just has these pulses inside it. Ngl it's a cool detail that changes how we model things like rivers, but the big takeaway is still millions of years.
Reading that Utah study actually changed my mind. I used to picture it as one constant grind, but @charlie_roberts87 is right, those little speed-ups make sense. It's like the land takes a deep breath every now and then.
Yeah, @charlie_roberts87 is right about the scale. I read that too, and those "fast" bursts are still like a foot of erosion every hundred years. It just means the old models were a bit too simple, not wrong.
