Extent of the Mesa Falls ash bed

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]
