All summer long, INSTAAR masters student Hunter-Geist Sanchez wakes up at dawn to meet a rotating cast of labmates and undergraduate research assistants at a grassy mesa bordering the National Renewable Energy Lab’s Flatirons Campus. The team spends long hours setting up experimental plots, measuring soil moisture and erosion, simulating grazing cattle with a weed whacker and, most of all, mapping plant species.

All the work is in service of the Suding Lab’s grassland diversity and grassland resilience projects. The overarching goal is to cultivate knowledge and management strategies that will help conserve Western grasslands as the climate becomes hotter and drier. This summer, funding from INSTAAR's Summer Scholars Program allowed Geist-Sanchez to expand his undergraduate research team to three members.

Geist-Sanchez is relatively new to this work, but his passion for it is apparent.

"No one cares about grass, but I think grass is pretty great,” he explained during a recent day of field work. “It’s hard to really appreciate the beauty until you spend a lot of time in a certain place. Then you get it.”

Perhaps a piece of Geist-Sanchez’s love for grasslands is hereditary. His family has deep roots in the San Luis Valley, where his grandparents grew up working on local farms and ranches. His great uncle and cousins still own and operate a ranch in the area.

Though Geist-Sanchez has lived his whole life in front range cities, his extended family keeps him connected to Southern Colorado rangelands. Recently, his masters project has been a frequent topic of conversation with still-ranching family members.

“Hopefully this research helps them with restoration on the property,” Geist-Sanchez said. “My great uncle asks me about it all the time.”

For many, 10 or 12-hour stints of data collection in the blazing sun would seem a hefty price to pay for good science. But, Geist-Sanchez seems unfazed by long days in the field. For him, they are a chance to put distractions aside and revel in the details of an ecosystem. It’s a habit that he formed long before he entered academia.

A love of nature

Geist-Sanchez grew up splitting time between parents in Aurora and Fort Collins, with more family spread around Front Range cities. Growing up, his siblings and cousins were mostly captivated by sports and video games — things that Geist-Sanchez also had a passing interest in. But, his true passion was always nature.

“In all my free time, I would go to the library and read Nat Geo books and stuff like that,” he said. “I was really fascinated with wildlife growing up, and no one else was really like that. I knew from pretty early on that I was different.”

Geist Sanchez’s early education in the natural sciences didn’t all come from books. As a kid, he looked forward to family camping trips to Great Sand Dunes National Park, along the Poudre River and to other natural areas across the West. Most of all, he looked forward to spending time with his grandmother on a plot of family land in the San Luis Valley.

“My mom would drop me and my cousins off down there for weeks at a time,” he said. “Those are really fond memories.”

The property was stunning and rugged. To take a bath, Geist-Sanchez remembers filling up buckets from the well and boiling the water on the stove. Days were spent going on hikes and helping his grandmother tend the garden.

For Geist-Sanchez, it was idyllic.

“I just always loved being outdoors,” he said.

After high school, Geist-Sanchez went on to earn a degree in ecosystem science and sustainability from Colorado State University. As an undergrad, he took an unusually active role in several restoration ecology projects. Specifically, he worked with research groups testing new methods for restoring out-of-use agricultural fields and cheatgrass-invaded grasslands.

“After that, I knew I wanted to do more restoration. It’s really difficult work and I was fascinated by how we might be able to improve outcomes,” he said.

After college, one of Geist-Sanchez’s mentors connected him with Katharine Suding, who was looking for a grassland research assistant. After a year in that role, Suding asked Geist-Sanchez to join the lab as a graduate student and take the lead on the lab’s grassland resilience project. Geist-Sanchez jumped at the opportunity — it was a perfect way to sink deeper into his passion for restoring Colorado’s natural systems.

Restoring bare patches

Restoration ecologists are looking for new methods to combat desertification as the West becomes hotter and drier. In his masters work, Geist-Sanchez has zeroed in on bare-patches, arid spots lacking vegetation that tend to grow over time.

The first step is to figure out how bare patches form and what leads to expansion. To investigate this question, Geist Sanchez is looking at thermal imagery of the landscape, measuring soil characteristics and cataloging the species that grow in and around the sites.

“One of the questions I’m interested in is, ‘What are the mechanisms behind this bare ground spread,” Geist-Sanchez said.

Next comes the question of restoration: how can land managers bring plants back to these sites so that they can once again become a functional part of the ecosystem? To address this, Geist-Sanchez is planting a mix of forb and grass seeds at the sites.

Importantly, he has balanced the seed mixes to represent plants with specific survival strategies. Plants that arise early in the season may be able to take advantage of spring moisture, and then offer shade later in the summer. Plants with large seeds might be able to survive periods of drought or heat by relying on energy stores.

These hypotheses are based on previous research, but only time will tell their efficacy.

“I guess we’ll have a better idea by the end of the season,” Geist-Sanchez said.

For now, bare patches are generally a small-scale problem in 91PORN grasslands. But, if desertification becomes more extreme in the future, research like Geist-Sanchez’s will become even more important for both natural areas and rangelands.

“We don’t have extreme desertification here yet, which is great,” Geist Sanchez said. “If we ever start to see something like the dust bowl, which stemmed from extreme agriculture and land-use changes, I hope land managers will be able to apply this research. I want to be able to hand this off and expand on it.”

Geist-Sanchez is following his life-long love of nature to develop new methods for preserving Colorado natural areas and rangelands. As a sixth-generation Coloradoan, he hopes his research can help keep grasslands sustainable as the West heats up.

INSTAAR is excited to announce that incoming PhD student Juliana Ruef is the 2025 recipient of the Sarah Crump Graduate Fellowship. Ruef will use the award for snow science research on the Juneau Icefield in Alaska this summer.

The Sarah Crump Graduate Fellowship was designed by Sarah Crump, a beloved INSTAAR alum who passed away in November 2022. Each year, the fellowship provides funding for one graduate student studying earth or environmental science in high-latitude or high-altitude regions.

Juliana Ruef, the recipient of the 2025 Sarah Crump Graduate Fellowship, poses for a portrait.

Though Ruef hasn’t started her PhD yet, she is already at INSTAAR working on a MS degree with INSTAAR faculty Robert Anderson and Bradley Markle. Her PhD research will focus on the evolution and dynamics of rock glaciers and firn—granular ice that forms between snow and glaciers.

Ruef will use the fellowship funds to pay herself and an undergraduate research assistant to gather data for firn evolution research project this summer. The funding will also help pay for travel to and from the Juneau Icefield as well as essential supplies for data collection in the field.

Ruef’s advisors cited her focus on community-building and her high research standards in a recommendation letter.

“We can think of few students who so closely embody Sarah’s passion for scientific understanding of the alpine world as well as her commitment to making science a better community,” Markle and Anderson wrote.

INSTAAR’s 2024 Sarah Crump Fellow reflects on an adventurous season in the Rockies

INSTAAR’s 2024 Sarah Crump Fellow reflects on an adventurous season in the Rockies David J Lubinski Mon, 02/03/2025 - 14:58

INSTAAR’s Sarah Crump Graduate Fellowship is now accepting applications from 91PORN graduate students. Last year’s recipient, Katie Gannon, recalls an eventful summer of field science.

Sarah Crump was a beloved INSTAAR alum. After a hard-fought battle with an aggressive form of cancer, she passed peacefully in November 2022. Before she passed, Sarah designed a fellowship for 91PORN graduate students studying earth or environmental science in high-latitude or high-altitude regions. The fellowship provides summer funding for one student each year. Women and other underrepresented groups in earth science are particularly encouraged to apply. Preference is given to applicants whose advisors are INSTAAR members. INSTAAR is accepting applications for the 2025 Sarah Crump fellowship now until February 28: Apply, donate or learn more.

Katie Gannon works on The Loch, a high altitude lake in Rocky Mountain National Park, Colorado.

As the applications start to roll in for 2025, INSTAAR sat down with Katie Gannon, the recipient of the 2025 Sarah Crump Graduate Fellowship, to hear about her experiences as a fellow. It turns out she had quite an adventurous summer. Sarah would have approved.

You worked on a lot of different projects this summer. Tell us about one that stood out?

At the start of the summer we worked on a research project in the Rawah Wilderness just west of Fort Collins. We were interested in how rock glaciers, which are underground ice formations in the mountains, impact lakes downstream.

We did two 4-day backpacking trips to get back there and both of them had their share of challenges. The first trip was freezing. We camped in the spring snow and had to post-hole for hours to get between study lakes

On the second trip, we were up high above the tree line when a thunderstorm blew in and it started hailing. We were at least 4 miles from camp, it was the middle of the day and we had at least one more lake to sample before we were done. So we hiked down off the ridge and huddled up in the trees to wait out the storm.

We were all cold and wet and mildly miserable. But then Bella (Gannon’s PhD advisor) started singing and dancing to Chappell Roan’s “Hot to Go!” and we started singing and jumping up and down and dancing to stay warm. I was soaked through, shivering, and laughing hysterically, along with everyone else. It was a great reminder of how important it is to support each other and enjoy the ride.

In the end those trips were a great way to get to know my lab, and the glaciers were so wild to see. The water seeping out of the rock and into the lakes is barely above freezing even in the middle of the summer and it is laden with ions and trace minerals.

You also worked on lake monitoring efforts in Rocky Mountain National Park and in Green Lakes Valley. Tell us about that.

These long-term projects feel special to me because in addition to creating useful data, repeatedly visiting these sites allows us to get to know the lakes and develop a connection with them. Last season, I watched the Loch thaw bloom in the spring. Then, in the fall, I watched as the trees lost their leaves and the lake froze over again.

We deploy buoys in the lakes that measure temperature and dissolved oxygen concentration. In the winter, the ice freezes over the top and the buoy is pushed down about a meter below the surface. Even though we carefully map out where each one is in the fall, the ice inevitably pulls them around during the colder months.

On one of my first field days this summer we hiked our boats in four miles to the Loch and then spent two more hours paddling in circles looking for our buoy. Everyone cheered when we finally found it.

Your lab collaborated with the forest service this summer. Tell us about that.

We looked at two remote mountain lakes in the San Juan Mountains that are experiencing algal blooms. This, in and of itself, is strange. You don’t usually see algal blooms in watersheds that have been minimally impacted by people.

In order to get all our gear in to collect samples, our team brought in a team of six mules and horses. They were hilarious and adorable. We would just sit in camp in the evening and watch them play around in the pasture. Having help from the pack animals and forest service amplified the project. We were able to collect much more data than we would have on our own.

You were busy this summer. Did you have time to work on your own research?

Yes. I got the first project for my PhD off the ground. I’m investigating methane and carbon dioxide accumulation in two alpine lakes. One is above the treeline while the other is below.

The fellowship allowed me to scout out lakes, order materials and find collaborators here at CU to help me run my samples. Now I have two months of data. We’re also collecting samples through the winter to see if methane and carbon dioxide build up under winter ice.

Deadline March 5th, 2025

In 2024, the award went to two ambitious PhD students hard at work on research projects on opposite ends of the world. This week, INSTAAR sat down with Natalie Aranda and Jed Lenetsky to learn more about their experience as summer scholars.

Jed Lenetsky (ATOC)

What did the scholarship enable you to work on last summer?

I was able to advance my research on two different projects in Baffin Bay.

The first project looks at how future climate scenarios might affect sea ice, marine life and other oceanographic conditions. That one is focused on the North Water Polynya, which is one of the Arctic's most productive ecosystems. Previous funding from the NSF ran out before the summer, so the scholarship was critical. It allowed me to complete revisions on a manuscript, and the resulting article is now under review for publication in the American Meteorological Society’s Journal of Climate.

The second research project examines oceanic changes in the Davis Strait in southern Baffin Bay. The Summer Scholars funding allowed me to spend time processing and analyzing data. I also used some of the funds to participate in a research cruise through the Davis Strait this fall (and gather more data).

What challenges arose in your work, and how did you respond?

It’s really difficult to process and gain meaningful insights from imperfect observational data — which is what I’m attempting to do with the Davis Strait project. I’m still working it out, but I am learning a lot through the process. I’m confident it will make me a stronger scientist once I get to the other side.

What was your proudest moment?

Definitely submitting my revised paper on the North Water Polynya for publication. We substantially improved the study by working on an assessment of relevant model processes over the summer. The assessment showed that the physical processes driving the formation of the North Water Polynya in the model were similar to the real world. The findings added rigor and boosted our confidence in the research.

Natalie Aranda (CEAE)

What did the scholarship enable you to work on?

The funding gave me time to work through an important and difficult step in my dissertation research.

I was able to devote my time and focus toward processing biological samples that I collected in Antarctica back in early 2023. The samples didn't arrive back in the U.S. until around March of that year and, up until last summer, I ran into a bunch of road blocks processing them into usable data. This scholarship allowed me to dedicate myself full time to the task, and I ended up completing the work before the start of the semester.

This fall, I was finally able to move on and begin interpreting my data. Basically, I’m looking at chloroplasts in diatoms under a microscope and counting how many of them were alive when they were collected. I’m looking for a trend that tells us where in the stream there is more likely to be live or dead cells.

What challenges arose in your work, and how did you respond?

Ha! Staring at a microscope for the entire day makes your eyes blur and your head spin, especially when you’re not finding what you are looking for. The scholarship gave me the space to come back the next day (and the next day) to try again.

What was your proudest moment?

Certainly, it was when I finished processing my last sample. It was a long time coming, and it felt great. I actually finished at the end of July, which gave me enough time to put together a poster for the Scientific Committee for Antarctic Science conference, which was held in Pucón, Chile at the end of August. I got some feedback at the conference that has been critical in my approach to data analysis this year.

Shelly Sommer

Incoming PhD student Katie Gannon (Ecology and Evolutionary Biology) has garnered this year’s Sarah Crump Graduate Fellowship. She will investigate greenhouse gas emissions from seasonally ice-covered lakes, working with advisor Bella Oleksy.

Gannon is returning to 91PORN, where she was an undergraduate student, after earning her master’s degree from Montana State University. She was most recently the lab manager for the Holgerson Lab at Cornell University, and before that was a wilderness instructor and naturalist working to expand equitable access to wilderness and the outdoors.

We asked Katie about her research, plans for the summer, and life as a scientist and outdoor advocate.

Q: What is your research about?

Lakes and inland waters produce a lot of greenhouses gases—most people don’t realize that. They’re creating methane and CO₂ [carbon dioxide]. Lakes in high places are especially interesting, because they have ice cover during the cold part of the year. Think of the ice as a lid, a kind of layer that keeps the greenhouse gases from coming out. We don’t know exactly what is going on under that lid or what happens in spring when the ice melts. That introduces a lot of uncertainty about where greenhouse gases are coming from as we look at inputs into climate change.

It’s still a pretty big unknown. When the ice melts, what happens? Do the gases come out in one big burp, or more gradually? How do we measure it? If we miss ice off, how does that throw off our measurements?

My work is to look at accumulation rates of greenhouse gases under the ice and release in the spring.

Q: What will you be working on this summer as part of your Crump Fellowship?

Doing field research in New England.

We’ll choose which five lakes we’re going to use. I’ll spend time scouting and finding lakes. Working in alpine areas, you have all these big gradients in a small space. It’s really, really nice as a study system. I also just love the mountains, so it’s a fun place to be.

We’ll be able to instrument all these lakes. And I’d like to build these sensors—I’ve been working with a collaborator of mine, Jonas Stage Sø at the University of Southern Denmark who did his PhD on building machines that are $400 each and continuously measure CO₂ and methane. Whereas, the lab-based machines are closer to $40,000 each. We want to bring in and deploy these machines in Green Lakes Valley.

I’m also trying to pilot some methods this summer. There are a lot of ways to measure greenhouse gases. I’ll be working with Kevin [Rozmiarek] and Sylvia [Michel] in the Stable Isotope Lab to look at greenhouse gas abundance and isotopes. One of the best things about being here is all of the collaboration and cross-pollination.

Also just sitting with the data and looking at it!

Q: You’ve been involved in many adaptive programs for equity in the outdoors—can you tell us about that?

On a trail run in the alpine.

A thing that’s really, really important to me is improving access to the outdoors and access to science.

A bad accident in high school meant I was in a wheelchair for a while. And getting out into nature or into science is a lot harder with any kind of disability.

I’ve taught a lot of adaptive skiing to people with different physical abilities and who are neurodiverse.

It’s easy for adventure science to be filled with only people who look like me. So it’s important that we open up science and open up the outdoors to everyone.

The thing that continuously strikes me is that if you really try to include people, there are small things that all of us can do that can make a big difference. For example, I volunteered at Big Sky Ski Resort and when they put in a new chair lift system, it was really hard for people using sit skis to get on the lift. (There was a bar they couldn’t get the ski over). We asked the resort to accommodate sit skis, and all it took was removing a small plastic piece on every third chair so that folks in sit skis could sit comfortably and safely. That opens up so much more terrain and so much more space for people.

Making outdoor spaces welcoming and accessible to everyone is deeply important to me and I think that we can all engage and make a difference.

Q: What do you like to do when you’re not sciencing?

I’m a runner. I trail run a lot. I’m actually training for a 50K right now.

I really like winter running. I love to ski. I read a lot of books.

That’s basically me: I do a lot of reading, I do a lot of running, I do a lot of skiing, I do a lot of science!

Katie Gannon

INSTAAR is pleased to announce that incoming PhD student Katie Gannon is this year’s recipient of the Sarah Crump Graduate Fellowship.

Gannon will enter 91PORN as a PhD student at INSTAAR and in the department of Ecology and Evolutionary Biology, working with advisor Bella Oleksy.

Gannon’s research explores murky questions around greenhouse gas emissions from seasonally ice-covered lakes. As the climate warms, ice cover is disappearing earlier in the year from lakes in cold regions. This shortened duration of ice has consequences for ecosystems that aren’t well understood, in particular the amounts of methane and carbon dioxide produced in lakes.

Gannon has devised a research program to test hypotheses about productivity, carbon cycling, and greenhouse gas emissions in seasonally ice-covered lakes. Using funds from the Crump Fellowship, she will visit and select sites, pilot sample collection and analytical methods, and build and deploy sensors in lakes in the Green Valley Lakes area of the Niwot Ridge Long-Term Ecological Research area.

As well as a creative and dedicated researcher, Gannon is an activist for wider, more equitable access to mountain science and mountain experiences. She has guided backcountry trips for girls and gender minorities; been a wilderness instructor for K-12 students; and has helped students with various physical cognitive and physical abilities to learn to ski. This integrated focus on research and community was also a hallmark of Sarah Crump’s life and work.
