Chira Endress, a student of Dickinson College in Carlisle, Pennsylvania, United States, focused on a section of glaciogenic sediments immediately beneath the same Ice Peak trachyte lava flow sampled and described by Jeff Hungerford during his 2006 studies. Endress attempted to determine if the sediments were deposited immediately before the lava flow was emplaced, or if they are likely to be much older. Endress has quantified the mineralogy of clasts and sand-sized particles from samples in the sediment, and has determined that the mineralogy of several of the trachytic clasts is very similar to that in the overlying lava flow, including the minerals clinopyroxene, magnetite, alkali feldspar, and aenigmatite. Endress has also found small lenses of pristine basaltic glass, which could have derived from the Pillow Ridge subglacial mound near Mount Edziza.
