INSTAAR's 75th anniversary (1951-2026)
75 years of discovery on top of the world
Join us in celebrating INSTAAR's history of groundbreaking research and education, plus all the amazing people who made it happen.Ìý
We also need your help to launch our next 75 years. Please consider donating, in any form or amount, to one of our funds supporting the people, equipment and resources behind our work in service of a thriving world:
INSTAAR’s mission to study the causes and consequences of environmental change has never been more important as our planet experiences an unprecedented temperature shift. At the same time, the funding sources we traditionally rely on have become limited and uncertain. Despite these challenges, INSTAAR remains steadfast in its pursuit of scientific excellence. In our 75th year, we are calling on you, our community, to celebrate our history and help further our mission.
INSTAAR leads groundbreaking environmental research in the arctic, antarctic, alpine, oceans and beyond. Our work is interdisciplinary and forward-thinking — experts across scientific fields collaborate on complex problems, and students and postdoctoral trainees transform into scientific leaders.
Our research strengths include:

Anniversary events
Join us in person or online for our 75th anniversary event series throughout 2026. Diane McKnight will kick off our "women of INSTAAR" seminars with an evening talk about her extensive experience studying the biogeochemistry of lakes and streams of Antarctica. If attending her talk via Zoom, be sure to . In the summer, the Mountain Research Station will host an open house as well as a series of research talks.
Check in here for more events and info throughout the year.
Our history
Inaugurated in 1951, INSTAAR is one of the oldest research institutes at the University of Colorado. Its origins extend back farther, to the Mountain Laboratory in Tolland, Colorado (1909–1919), and to University Camp located near Niwot Ridge, Colorado (1914–1920). In the early 1920s, research moved from University Camp to the present site of the Mountain Research Station, which remains an important field station supporting INSTAAR research.Ìý
We will be adding a deep dive into INSTAAR's past to this page soon. Keep your eye out for theses, timelines, photos, and more.
In the meantime, check out our 107-page booklet 50th Anniversary: The Institute of Arctic and Alpine Research 1951–2001 (PDF). It covers INSTAAR's history extensively through 2001, including personal recollections.

Help INSTAAR launch our next 75 years
Ìý
Our institute was founded in 1951 by John Marr, a young ecologist with a passion for the living organisms intrepid enough to survive harsh winters high in the Rockies. Capitalizing on a national wave of interest in scientific prominence, INSTAAR soon expanded its operations to become a global leader in environmental research. Today we need your help more than ever to continue this work.
In honor of our 75th anniversary, we invite you to climb with us toward discovery on top of the world.
Donations to the following funds go directly to the people, equipment and resources behind rigorous scientific investigations in service of a thriving world.
Future Forward Facilities Fund
INSTAAR houses more than 20 unique laboratories with state-of-the-art equipment maintained by expert technicians that unlock breakthrough research. Many of our facilities feature one-of-a-kind instruments developed in-house by our teams.
Laboratory equipment and personnel are critical to our research. Your gift to our facilities fundÌýwill expand our capabilities, upgrade one-of-a-kind instruments, and sustain expert staff. Working together, we can bridge the gap between ‘what if’ and ‘here’s how’.
Our lab capabilities are vast. We measure chemicals and their isotopes, extract DNA and other organic molecules from environmental samples, detect rare elements and compounds, and identify microscopic organisms. ÌýINSTAAR’s walk-in freezer stores ice cores from Antarctica and Greenland, preserving a climate record that extends backwards for hundreds of thousands of years. Our radiocarbon laboratory turns air samples into solid graphite so they can be measured on a powerful mass spectrometer.

New Frontiers Faculty Fund
INSTAAR faculty have deepened humanity's understanding of cold regions vastly over the past 75 years, thanks to a steady stream of support from federal agencies such as the National Science Foundation. Unfortunately, federal support for the kind of high-risk, exploratory studies that produce truly ground-breaking science has dwindled.
Your gift to our faculty fund will launch ambitious forward-thinking science at the far ends of the world. These seed funds will empower our faculty to grow exploratory thinking into large-scale, impactful research projects.
Our researchers often start with big open-ended questions. Where are the most important hotspots for life in Antarctica? Or, how does water quality change over the length of the Colorado River? (to name two). Funding for these types of investigations requires foresight beyond short-term economic time scales. But the answers to these questions also have an outsized impact on scientific progress, societal wellbeing and the health of our planet.

Poles to Peaks Postdoctoral Fellowship
Cold regions are changing faster than anywhere else on Earth, and our institute is uniquely positioned to study these changes, predict their impacts, and propose solutions. Help us mentor the next generation ofÌýinterdisciplinary scientists working on the front lines of climate change.
Your gift to our postdoctoral fellowship fund will bring the best and brightest young scientists to INSTAAR to help us plan for our planet’s future. It will also broaden interdisciplinary collaboration at INSTAAR — connecting scientists across fields through mentorship.
Our research spans many fields, including aquatic and hydrological sciences; atmospheric, oceanic, and climate sciences; ecology and evolutionary biology; environmental and mechanical engineering; and cryospheric, geological, and geographical sciences. Innovative science comes from crossing these disciplinary boundaries and exchanging ideas.

Other ways to climb with INSTAAR
Did you know that global standards for CO2 are calibrated right here in Colorado? The MRS hosts the longest continuous CO2 record in North America (third longest in the world). And that’s just one of many programs from the station’s 105-year history that have shaped how we look at the world.Ìý
From the Niwot Ridge Long-Term Ecological Research Program to the ¶¶Òõ´«Ã½ÔÚÏß Creek Critical Zone Program, these long-term research projects tell us not only how the planet has changed in the past, but how it might change in the future and what we can do about it. Your support will help faculty, students, and visiting scientists expand our knowledge of high-alpine environments.
Spruce Gulch is a living laboratory, providing locally relevant research and educational opportunities for scientists, students, K-12 educators and nonprofit groups. Spruce Gulch is INSTAAR’s newest acquisition, thanks to a generous donation, and is also Colorado’s first-ever research reserve in a Front Range foothills ecosystem.
The reserve is home to a pristine watershed, making it a unique site for ecological and hydrological research. Its beauty and close location to CU ¶¶Òõ´«Ã½ÔÚÏß campus also make it an excellent site for experiential learning in the humanities, social sciences, architecture and the arts. Your support will help launch research and education efforts that have a direct impact on ¶¶Òõ´«Ã½ÔÚÏß and the surrounding area.
