Mesa Falls Tuff

Extent of the Mesa Falls ash bed.

Mesa Falls Tuff exposed at southern rim of both the Island Park Caldera and the Henry's Fork Caldera near Ashton, Idaho.
The Mesa Falls Tuff is a tuff formation created by the Mesa Falls eruption that formed the Henry's Fork Caldera that is located in Idaho west of Yellowstone Park.[1] It is the second most recent caldera forming eruption from the Yellowstone hotspot and ejected of 280 km³ 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 created by the Yellowstone hotspot.[2]
