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:
