San Gabriel Mtns Geomorph Research Project

San Gabriel Mtns Geomorph Research Project

Geomorphology Field Research Project: Mountain Front Faulting & Alluvial Fans San 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 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 Project Overview Integrates learning in:

fluvial geomorphology Quaternary stratigraphy

soils & weathering tectonic geomorphology

climate change landscape evolution San Gabriel Mountains

Project Goals The students will integrate and apply their geomorphology course learning through independent research

Project Goals The students will develop skills in:

teamwork project design

literature review fieldwork

data analysis interpretation

report writing oral presentation Project Goals The students will

learn to think like a Geomorphologist ! Project Study Area: San Gabriel Mtn. Foothills

Fault Map of Study Area: From a student report Aerial Photo of Study Area: Taken by students in the class Suburban sprawl along mountain front thrust faults

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

Field Techniques & Skills A few examples 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. 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 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 Allison Ruotolo & Rob Ellis presenting their project results 2006 GSA Cordilleran Section Meeting, Anchorage, AK The end.
