An isolated fjord at the edge of the Southern Patagonia Icefield. A small cluster of tents pitched beside Bernal Glacier. Fourteen days without roads, cell reception, or routine – only creaking ice fronts, restless wind, the constant murmur of meltwater, unrelenting rain, and a team of fellow adventurers as companions. The Patagonia Icefield Research Program (PIRP) is an immersive classroom where students and early-career researchers learn directly from the landscape and the glacier itself. This is our adventure diary from the 2025 expedition.


What is the Patagonia Icefield Research Program?

The following story is about a group of early career researchers, faculty, and staff who spent 14 days camping near Bernal glacier in Patagonia. During this time, we learned and practiced a range of fieldwork techniques, including radar surveys, glaciological measurements using ablation stakes, glacier boundaries reconstruction from historical data, and taking sediment cores.

We were part of an initiative called the Patagonia Icefield Research Program (PIRP). The 2025 campaign was the fifth in the history of the program and the second one on Bernal glacier; the previous three took place on Grey glacier. The program is run by Dr. Camilo Rada and Natalia Martinez and was originally created to give Master’s students from the University of Magallanes (Chile) hands-on experience working on different glaciological research projects. In the last two years the program was expanded to include applications from students from around the world. The goal of PIRP is to provide a genuine glacier fieldwork experience – raw, unpolished, and both physically and emotionally demanding. Fieldwork in Patagonia means facing nearly constant rain, freezing temperatures, mud, and exhaustion, and even learning to dry wet gear using only body heat, all while carrying out real scientific research. The program brings together students from different nationalities, cultures, and levels of mountain experience, ranging from complete beginners to seasoned adventurers. For most participants, it is also the first time setting foot on a glacier.

The individual student projects span a variety of disciplines, from geology and glaciology to science communication, giving each student the opportunity to work on the projects that interest them the most. In 2025, the team consisted of nine faculty mentors and staff and eleven students (Master’s and PhD students) Of these, ten were international, coming from Colombia, Bolivia, the United States, Germany, India, Nepal and Argentina, and the remaining participants were Chilean. Most of the students were Master’s students from Chile and the international students were PhD students.

Preparing for the Adventure

Our story begins in Puerto Natales, Chile, where we spent the first few days in a picturesque guest house called “Casa Raky”. Here is where the national and international students first met each other, along with the faculty mentors and staff. During this time we had many opportunities to exchange experiences and learn about each other’s cultures over shared meals and long nightly conversations as we shared rooms. We also went into town together to buy ingredients and prepare dishes from our different cultures, for example one evening we helped prepare Chai Tea.

During the days at Casa Raky, we learned how to use the safety equipment required for working on the glacier, how to set up the tents, and practical tips on how to pack our gear. We were also introduced to “leave no trace” principles and the clothes layering system that would help us stay warm and dry in the field. In parallel, everyone began preparing materials for their individual projects or buying any missing clothes or equipment. We stayed two days at Casa Raky because we had to wait for a suitable weather window without too much wind and rain that would allow us to travel safely by boat to the glacier. Patagonia is a place with highly variable weather, where strong winds and heavy rain can appear suddenly and change conditions from one moment to the next.

Journey to Bernal Glacier

After our days of preparation for the field, we were finally ready to head into the field. The glacier where we would be working is called Bernal Glacier, located in the Sarmiento Range below the Southern Patagonia Icefield. Reaching it required a three-hour boat trip. On the way, we could see the beautiful landscape, flora and fauna of the Patagonian wilderness. As we moved deeper into the fjord, glaciers along the mountain range gradually came into view.

The boat trip ended when we arrived at a remote beach and started unloading equipment and provisions from the boat. Once everything was on shore, we were paired to share the available tents. The camp was set up in the nearby forest and we pitched our tents on wooden platforms that Camilo and Natalia had built to keep them from possible flooding and started unpacking our backpack. This was the moment when the real adventure started.

Patagonia as a Classroom

The first week at camp was packed with workshops designed to teach us how to use the various instruments and techniques required for glacier research, covering both practical skills and theoretical knowledge. The workshops were done at different places, some at the camp but most of them in the proglacier zone and on the glacier, which meant carrying all the necessary heavy equipment with us, including ice augers, a hot-water drill, sediment core extractor, and our safety gear. As the glacier landscape is constantly changing, a path that had been usable last year was now completely blocked due to glacier retreat, forcing us to take a longer, more challenging route that involved crossing rivers, navigating slippery rocks, and scaling the side of a mountain.

On the glacier, one of the most memorable workshops was the hands-on session where we learned how to use the instruments required to drill into the ice – both manually and with hot-water drilling systems – to install ablation stakes. Bernal Glacier has complex and very steep topography, and some groups working farther up the glacier needed to climb sections of ice to reach their study sites. For this reason, we also had an ice climbing workshop along the glacier’s vertical walls. For most of us, this was the first experience climbing an ice wall. Despite the demanding approach and complex glacier terrain, these experiences were some of the most rewarding parts of the expedition, giving us a true sense of what working in glacier research really entails.

Time to do some Measurements

During the second week, we put our training into action, diving into our projects under the guidance of the faculty mentors. Each student worked on an individual project while collaborating and supporting one another across teams. Some teams focused directly on the glacier, for example, by measuring surface melt and daily ablation at different points using stakes.

They also studied how ice albedo – how dark or light the ice is – and debris cover affect local melt rates. Other teams mapped supraglacial rivers and analyzed water flow, and another used ground-penetrating radar to examine ice thickness. Teams in the proglacial environment focused on studying the landscape and processes beyond the ice itself. They collected cosmogenic samples from different glacier erratic blocks to understand the glacier’s history, conducted bathymetric surveys to map lakes, captured drone imagery for geodetic mass balance, and sampled river sediments to analyze material transported by meltwater. Another project focused on science communication, developing interpretive sign displays for tourists that visit the glacier, explaining the environment, glacier dynamics, and climate change. They also reconstructed historical images and timelines to illustrate the glacier’s evolution over time. The projects were truly diverse, and evening debriefings offered an exciting opportunity to share insights and learn from each other’s work.

Sharing our experiences with the Puerto Natales community

With heavy hearts (and backpacks) we sadly saw that our days in the camp had come to an end. We packed our equipment and prepared for the same trip that we had taken 14 days earlier to return to Puerto Natales. After taking the first shower in a few weeks, we went out to celebrate the end of the field experience with a special Patagonian dish, a lamb, prepared just for us.

The end of the expedition was not only about eating lamb, resting, and enjoying the city. As we arrived, the students started processing the data collected in the field and preparing slides for the final presentations. The program concluded with a public presentation for the Puerto Natales community at Mulato Cafe, where the students shared some of their results and their experiences during the days spent at camp. The event had a good turnout and the audience was very enthusiastic about listening to our adventure. The international students were brave enough to give their presentations in Spanish (after only two days of practice!).

Reflections

Bernal Glacier was more than a research site: it became a temporary home where students from around the world gained technical skills, resilience, adaptability, and practiced their ability to work together in demanding conditions. The challenges, teamwork, and rapidly changing environment created unforgettable memories and lessons. As feedback, we heard from many students that the experience was truly transformative.

It is incredible what Camilo and Natalia have built with this program. They brought mountains of equipment and spent countless hours meticulously planning the trip. They constructed wooden platforms for tents, cleared paths, and even built a Tyrolean bridge to safely cross the river. Their dedication and love of learning set an inspiring example for all of us. 

We hope you enjoyed reading our diary as much as we enjoyed writing it and remembering about this awesome experience. We know that if some of the friends we made during the program read this blog, they will probably say that we miss too many details and funny anecdotes. And they would be right, but we preferred to just give a brief glimpse, so that future students can discover it for themselves without too many spoilers. We hope that this post encourages you to take a look at the summer school and maybe even decide to spend a few weeks in Patagonia. PIRP also offers some funding possibilities to help students participate, so make sure to take a look here. We hope to see you soon in Patagonia!
