  4. Landforms - Western Grand Canyon • Hurricane Fault – most active in Arizona • Vulcan’s Throne – Volcanism and lava dams in the Grand Canyon, 3 Ma to the present • Paleo-channels - that came from the Mogollon Highlands • Havasu Falls – continuous deposition of calcium carbonate in the water causes agradation and eventually waterfalls. • Surprise Canyon Landslide – Largest in Arizona
