Here are some photos of the ice drilling, and the site where we are working. All come courtesy of David Christenson, Greg Chmura and Ario Samudro, the video/photography team from Freeport McMoRan, which has been helping us with all phases of logistics.

We have drilled a second core through the ice to bedrock, and are done at our first site. Unfortunately, the helicopter that we need to move the heavy pieces to our second planned spot is down for regular maintenance until next Monday, June 21. That means the team must wait it out at the relatively sheltered “saddle… read more

Yesterday we completed our first ice core at the Northwall Firn Glacier, down to bedrock, penetrating 30 meters through the glacier, until we hit bottom. The ice seems to contain visible layers all the way down–a sign that yearly accumulations have been preserved, instead of melding into each other. This means we should be able to… read more

The Crotone Basin accumulated sediments for nine million years before the forearc uplifted above sea level. Each layer of sand, clay, and conglomerate in the basin contains information about the environment at the time that layer was deposited. About six million years ago, halite and gypsum were deposited in the Crotone Basin. Geologists refer to… read more

With the blessing of two wonderful days of clear weather, all our equipment was moved into place this morning. The ice coring can now begin. We anticipate finishing the drill assembly today and drilling by mid-morning tomorrow at three sites on the Northwall Firn glacier: the two “domes” and the saddle, where the team will… read more

The climate of the Crotone Basin is marked by cold, wet winters and hot, dry summers. We arrived last year, on our first trip, in the middle of a six-month drought that lasted from April to September. I love how life figures out a way to flourish. Flowers in a riverbed; Snails on a thorn… read more

This morning we were at our staging area at the Grasberg mine at 5 am, and were able to use the B3 helicopter to get ourselves set up. First trip up, our colleagues Keith Mountain and Vladimir Mikhalenko went to what we call the “saddle camp”—a spot between two peaks—where we will stage the first… read more

With the drills essential to our work apparently lost somewhere in transit, Lonnie and I finally backtracked to Jakarta–a five-hour flight–and found them sitting in an airline warehouse! Within 24 hours, we had them shipped to our staging site, and now we are ready to go.

Last year I was collecting a sample of sediment from a riverbed and spent the day walking up the Neto River to find a good location. When I finished, I noticed a road high on one side of the valley. I climbed to the road and found a tunnel with no lights inside. I looked… read more

We are currently taking samples of water and sediments from high-elevation lakes near the glaciers. Like ice cores from the glaciers themselves, these should contain substances that will help us understand the climate history of this region. The sampling is being done in conjunction with the Indonesian Institute of Sciences and the Indonesian Meteorological, Climatological… read more

We are staying at the high-elevation Grasberg gold and copper mine—not on top of Puncak Jaya—because some of our equipment has not arrived. We have 99 pieces out of the 106 we shipped, but unfortunately our ice drills are in the missing pieces, and we cannot do anything without those. We are working hard to… read more

Nano and I have arrived in the Crotone Basin, where we’re staying in a place that Italians call an “agriturismo,” which is like a bed and breakfast that also serves lunch and dinner. Our little place is unique even among agriturismos. It is called Canciumati (can-chew-ma-tea), a house with four generations living under one roof…. read more

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… read more

It is a brutal flight from New York City to Roma. I am a sucker for in-flight movies: things I would never watch in the real world, I am completely enthralled with during an overseas flight. The problem on this flight is that we arrive at 7:30am. We have a whole day ahead of us… read more
