A collection of ballistic types seen in the field. a An intensely altered breccia block is partially covered by the waning stages of the pyroclastic surge. b A near complete covering by the near-end stages of the surge blankets the breccia ballistic. c A solitary hydrothermally altered ballistic that has no clear sign of a ballistic crater, presumably due to crater infilling and/or near simultaneous ejection of ballistics and surge. d A clear ballistic impact crater within ~ 130 m of the inner crater wall
