THREE ARIZONAS

Speaker Series talk with David Gilligan

Cactus Country, Creeks Country, Canyon Country: what we call Arizona today is comprised of three distinct geographic regions that differ remarkably physically, ecologically, and culturally.  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.
