Episode 105: America's National Parks <br /> <br />Today on the Coolest Places on Earth: We’re motoring across America on an epic outdoor adventure to explore its greatest National Parks. We’ll climb Yosemite’s El Cap, cheat on Yellowstone’s Old Faithful, and uncover the reason these stones are moving by themselves across Death Valley. We’ll duck under amber arches, drive through giant redwoods, and get as close as we can to all creatures big, bigger, and biggest.
