Project Overview:

Rob Ellis and fellow student Allison Ruotolo are working on a joint research project investigating uplifted Pleistocene alluvial fan remnants along the active mountain front faults of the San Gabriel Mountains in Los Angeles County. Their study focuses on isolated deposits of “older alluvium” that occur either as fan-head remnants or fluvial terraces along the mountain front between San Gabriel and San Antonio Canyons. This project involves field mapping of alluvial gravels, description of stratigraphic sections, clast counts to identify gravel source areas, topographic surveying across fan surfaces and potential fault traces, mapping of the gravel-basement contact based on outcrops and well logs, and morphometric analysis to evaluate active tectonic deformation. Rob and Allison presented preliminary research results in a co-written abstract and poster at the 2006 Geological Society of America Cordilleran Section Meeting in Anchorage, Alaska. They are now working on separate aspects of this study for their respective senior theses.
