These regions are the Sonoran Desert, the Mogollon Highlands, and the Colorado Plateau. Join naturalist and explorer David Gilligan for a natural history deep-time-dive into what makes these three places so distinct, including their geologic evolution, biogeography, present-day vegetation, and the movement of cultures through time.
