The Greater Yellowstone Ecosystem contains the headwaters of the Green/Colorado, the Snake/Columbia, and the Yellowstone/Missouri/Mississippi. Join us on an adventure through watersheds, exploring how the topography affects drainage systems and why these watersheds provide life for humans and wildlife throughout the western United States. During this 30–45 minute virtual field trip, students join an educator on a journey revealing how water in the Greater Yellowstone Ecosystem has changed the landscape.
