Yellowstone has been the home to not one, but three large-volume explosive eruptions, two of which classifying as supereruptions (>1000 km3)! The first and largest one is called the 2.1 Ma Huckleberry Ridge tuff, with deposits that spread up the Madison Valley, and down to Idaho Falls. This talk will go into how this magma was configured prior to the eruption (spoiler: separate pods rather than large connected volume of material!) and discuss how the timing of the eruption can be teased out through geochemical techniques and field geology.

Madison Myers is a 2nd year Assistant Professor of Igneous Petrology, largely focused on the study of volcanoes, in the Earth Science department at Montana State University. Her research aims to reconstruct the conditions (temperature and depth) under which magma is stored in the Earth, and unravel the timing of volcanic processes (triggering the magma, stalling on the way to the surface, etc.) through the use of their erupted products.
