Rivers are the veins and arteries of the Rocky Mountains, feeding the animals that call these peaks home. Fed by glaciers and motivated by gravity, these waterways are split by the massive Rockies, which diverts flows to the Atlantic, Pacific, and Arctic Oceans. We'll follow the water as it melts off the glaciers, down thunderous waterfalls, filters through wetlands, sculpts the terrain, and finally flows out to the ocean, and learn how it affects the wildlife along the way.
