those are just types of geology you fraud!
New York caused by aliens, got it.
The driftless region of MN and WI being shaped by rivers isn’t… inaccurate, I suppose. More like “rivers due to nearby glaciers” which isn’t quite the same thing.
Many rivers begin with glaciers. The Colorado, Mississippi, and Rio Grande, for example, still receive glacier melt to this day
Passenger pigeons were responsible for the growth of America’s forest before we cut down all the trees and ate the birds into extinction.

What’s going on in the Adirondack mountain range in upstate New York?

Tried looking it up, it’s so new that nobody who knows has made a post about it yet. Slow day at work so I’ll try and crack the case via wikipedia or whatever

I’m posting this wild postulation in the hopes that someone corrects me.
Okay, so a billion years ago a volcanic plume tried to fuck up Michigan and failed, causing the Midcontinent rift system. Then it chilled out for awhile before getting squished by glaciers into going east and making the Adirondack mountains about 20 million years ago. Then it went west due to daylight savings time and made Yellowstone.
