Kristen LaMoreaux, another student of the University of Pittsburgh, focused on the emplacement of trachyte lava flows and domes. In 2006, LaMoreaux analyzed jointing patterns at Ornostay Bluff, a viscous series of trachyte lava flows on the western lava plateau of the Mount Edziza volcanic complex. LaMoreaux also examined trachytic lava flows from Koosick Bluff and Triangle Dome, a trachytic lava dome which last erupted during the Pleistocene period. Other studies by LaMoreaux determined criteria for understanding how lava flow thickness may or may not be an indication that the progress of a lava flow was impeded by an ice barrier, resulting in an unusually thick lava flow.
