Scouting the Glacier

Team members are now actively scouting by foot on Puncak Jaya, looking for the best drill spots, travel routes  and campsites. The man in red is Broxton Bird of Ohio State University. In brown, the appropriately named alpine veteran Keith Mountain of  the University of Louisville. At bottom: team leaders Dwi Susanto and Lonnie Thompson give a presentation on the project, while preparing to ascend themselves.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
