Field Trips for Undergraduate and Graduate Students
              The Geological and Planetary Sciences (GPS) Divison organizes international field trips every two years 
               2010 Southern Peru
              Led by Professors Rob Clayton, Mark Simons, and Jean-Paul Ampuero. Many unanswered questions remain in southern Peru, such as how did the Andes grow ? And where first? And why, despite a geologic history of more than 200 million years of continuous subduction, did the South American margin not begin to grow high topography until about 50 million years ago? The trip was sponsored by Shirley Kliegel (learn more)  
              
               
              
               2008
                Taiwan
              Led by Professor Jean-Philippe Avouac. Taiwan is a classic
                example of an active mountain range with beautiful active
                faults and a rich bedrock geology. Organized jointly with
                the Institute of Earth Sciences (Academia Sinica, Taipei)
                and the National Taiwan University (Taipei) (Guidebook) (learn more)  
              
               
              2006
                Tien Shan
                   
            
              
              Led by Professors Jean-Philippe
                Avouac and Rob Clayton with 20 students from Caltech
                and several students from Nanjing University in China
                participating. The trip was an introduction to the geology
                of fold-and-thrust belts using the Tien Shans as an example.
