"When the #GreenRiver carved through the #Uinta Mountains, it fundamentally changed the landscape of #NorthAmerica. Rather than flowing eastwards into the Mississippi, it became a tributary of the Colorado River, and its waters were redirected to the Pacific.
This rerouting altered the continental divide, the line that divides North American river systems that flow into the Atlantic from those that flow into the Pacific. In doing so, it created new boundaries and connections for wildlife and ecosystems.
The story of the Green River shows that processes deep within the Earth can have profound impacts for life on the surface."
