The Mesa Falls Tuff is a tuff formation produced by the Mesa Falls eruption that formed the Henry's Fork Caldera that is located in Idaho west of Yellowstone National Park.[1] It is the second most recent caldera forming eruption from the Yellowstone hotspot and ejected of 280 km3 (67 cu mi) of material. This eruption, 1.3 million years BP, was preceded by the Huckleberry Ridge Tuff and succeeded by the Lava Creek Tuff, both of which were also formed by the Yellowstone hotspot.[2]
