Impact Field
Studies Group

The Impact Field Studies Group is dedicated to:

(1) Facilitating discussion of field-based impact geology.
 
(2) Gaining additional expertise by facilitating visits to confirmed/suspected impact sites.
 
(3) Offering field work opportunities to students in planetary science.

Membership is open to students, faculty, and researchers interested in or who are actively conducting field-based research.  For more information on becoming a member, please contact Keith Milam at:  milamk@ohio.edu.
