Around 12,000 feet lies the ecosystem known as the tundra. It seems to be made up of various grasses and a few different species of animals including big horn sheep and marmots. Not much else. According to our guide, the tundra is so fragile that if it gets damaged, say from human interaction, it can take up to 150 years before the grasses fill back in and the damaged area returns back to it's original state. That's why you are not allowed off the roads that go through there. You can see in this shot that the road snakes through the tundra and moves along. There are very few stops, but the ones that do exist are just small turnouts.
