  1. Geomorphology Field Research Project: Mountain Front Faulting & Alluvial FansSan Gabriel Mountain Foothills, Southern, California Dr. Jeff Marshall - GSC 323 Geological Sciences Department Cal Poly Pomona University 2008 Cutting Edge Workshop: Teaching Geomorphology in the 21st Century Abbreviated Version for the Web

  2. Project Overview • Capstone project for required upper division Geomorphology course (GSC 323) • Students work in teams to investigate a local landscape system: Mountain front alluvial fans & terraces of the San Gabriel Mountains

  3. Project Overview • Integrates learning in: • fluvial geomorphology • Quaternary stratigraphy • soils & weathering • tectonic geomorphology • climate change • landscape evolution

  4. San Gabriel Mountains

  5. Project Goals The students will… • …integrate and apply their geomorphology course learning through independent research

  6. Project Goals The students will… • …develop skills in: • teamwork • project design • literature review • fieldwork • data analysis • interpretation • report writing • oral presentation

  7. Project Goals The students will… • …learn to think like a Geomorphologist !

  8. Project Study Area:San Gabriel Mtn. Foothills

  9. Fault Map of Study Area:From a student report

  10. Aerial Photo of Study Area:Taken by students in the class

  11. Suburban sprawl along mountain front thrust faults Sierra Madre fault scarp

  12. Mt. Baldy & San Antonio Creek Watershed An Iconic Southern California Landscape

  13. Red Hill Rancho Cucamonga Classic field site for Alluvial Fan & Fault Studies

  17. Project Logistics • Research teams of 3 to 4 students • Each team assigned a discrete field area • Two project lab sessions: • Week 2: Intro Field Trip • Week 8: Follow-up Trip • Teams work outside of class time to complete field and office work • Other activities & field trips on related topics

  18. Field Techniques & SkillsA few examples…

  19. Final Report • Professional Format: 5 Pages of Text, plus Illustrations & Reference List • Introduction, Methods, Field Observations, Data & Results, Discussion, Conclusions • Quaternary Geologic Map • Stratigraphic Column & 2 Cross Sections • Soil Profile & Terrace Longitudinal Profiles • Field Photographs, Sketches, data appendices, etc.

  20. Team Presentation • Professional Powerpoint presentation • 30 minutes long (during last lab session) • Each team member participates equally • Follow same organization as report • Use illustrations and photos effectively • Question & Answers: Class participation

  21. Project Outcomes For students: • Enhanced confidence • Their own geomorphic problem solving “Tool Kit” • Better understanding & appreciation of research • Grad school interest (?) For the professor: • New research questions & preliminary data • Senior thesis students • Better teaching “buzz”

  22. Allison Ruotolo & Rob Ellis presenting their project results 2006 GSA Cordilleran Section Meeting, Anchorage, AK

  23. The end.
