Large Igneous Provinces Earth history is punctuated by events during which large volumes of mafic magmas were generated and emplaced by processes unrelated to “normal” sea-floor spreading and subduction. These events are called Large Igneous Provinces (LIPs).
Colorado River Delta - The Colorado River Delta is the region of land where the Colorado River historically flowed into the Gulf of California, (the Sea of Cortez). The interaction of the river’s flow and the ocean’s tide created a dynamic environment, supporting freshwater, brackish, and saltwater species. Within the delta region, the river split into multiple braided channels and formed complex estuary and terrestrial ecosystems.

Yellowstone Plateau Volcanic Field Yellowstone's world-famous natural history is marked by such colossal volcanic events that their reflections in today's landscape are difficult to grasp and impossible to take in at just a glance, even for those familiar with the signs of past volcanism.
