Thompson Field Forums

Thompson Field Forums

Thompson Field Forums are named in honor of James B. Thompson, Jr., a GSA benefactor and professor emeritus at both Harvard and Dartmouth.

NOTE: The GSA Penrose Conferences and Thompson Field Forums are undergoing an upgrade. The new proposal process will be rolled out in fall of 2019!

As of November 2018 we are not accepting new proposals. Look for additional information at GSA 2019 Phoenix, 22-25 September. If you have any questions please feel free to contact Becky Sundeen ().

Upcoming Field Forums

Age and Carving of Grand Canyon: Towards a Resolution of 150 Years of Debate
Grand Canyon, USA
14–21 September 2019

Field Forum trips provide an informal atmosphere to

  • Capture the essence of discoveries or controversial topics via on-the-spot discussion of a particular geologic feature;
  • Exchange current knowledge and exciting ideas; and
  • Stimulate individual and collaborative research.

Topics should

  • Have a specific thematic focus;
  • Be geographically oriented;
  • Have a potential for further significant advances; and
  • Be under current investigation and active discussion.


  • Groups should be small enough (20 people min.) that all participants can examine the outcrops;
  • Groups should be large enough (40 people max.) to provide diversity and depth;
  • Length: Five or more days;
  • Participants are expected to attend the entire field trip;
