In The Rockies, Climate Change Spells Trouble For Cutthroat Trout
There's an unplanned experiment going on in the northern Rocky Mountains. What's happening is that spring is arriving earlier, and it's generally warmer and drier than usual. And that's messing with some of the fish that live there.
The fish is the iconic cutthroat trout. It's a native North American fish that thrives in cold, small streams. Explorer Meriwether Lewis of Lewis and Clark Expedition fame was among the first European-Americans to catch this spangly, spotted fish. He used deer spleen as bait.
