GYC strongly supports legislation that is introduced in the U.S. Congress, calling for protections for East Rosebud Creek, a spectacular stream that rushes off the granite shoulders of the Beartooth Mountains through undulating ranchlands. East Rosebud is a stronghold for native cutthroat trout.

High on the Yellowstone plateau, America’s three great western river systems are born. The mighty Missouri begins its journey in the northwest corner of Greater Yellowstone and absorbs the pristine waters of the Yellowstone, Madison, Gallatin, Clarks Fork of the Yellowstone and Wind (Bighorn) rivers before its confluence 2,000 miles later with the Mississippi. The Snake rises in the southeast corner of Yellowstone and eventually helps the Columbia roll on to the Pacific. And the Green — “The Mother of the Colorado” — begins its watery trek to the Sea of Cortez on the flanks of the Wind River Range. They are the lifeblood of Greater Yellowstone.
