StateIdaho
NameRhyolite flows; Late Pleistocene rhyolite lava flows of subunit 1f; Yellowstone Plateau
Geologic ageLate Pleistocene
Original map labelQpu1f
CommentsArea of Qpu1f corresponds to that of Mount Jackson Rhyolite on map ID100, which is dated 0.69 to 0.79 Ma (ID122), and is younger than Mesa Falls Tuff. The Moose Creek and Big Bear Lake flows of the Mount Jackson Rhyolite were after collapse of the second-cycle Henrys Fork caldera (ID123) of the Yellowstone Plateau volcanic field.
