The situation

What’s happening to Green River

The last free-flowing major tributary of the Colorado River winds through Desolation Canyon, Labyrinth Canyon, and some of the most spectacular river country on the continent. Oil and gas leases along its corridor threaten the water supply for 40 million Americans downstream. What happens to the Green happens to the entire West.
