Graveyard Desert. The episode is set in a rainshadow desert on the eastern side of Earth's only continent, 200 million years into the future. Wedged between this desert and the Global Ocean is a series of very tall mountain ranges (which are comparable to the Andes in today's world) which are tall enough to block even the most powerful storms. At this point in the future, there are no mammals, birds, reptiles or amphibians. There are very few fish.
