CRYSP Lab
We study snow, glaciers and ice and how they impact landscapes and hydrology. We employ a range of field and laboratory approaches to measure and model the many surface processes that are involved.

Coloradoans and our shared environment in times of challenge and change (CU OOE)
A collaborative exhibition tells the story of how Coloradans are experiencing interrelated challenges of fire, drought, and water and air quality in their communities. Artists (the CASE Fellows) partnered with scientists and communities to make visible the connections between Coloradans and their environment. Several INSTAARs acted as scientist partners. This website showcases the artwork, as well as quotes from the partners, explorations of the issues, and what you can do to act. Read more
Scientists are using lasers to uncover the secrets of Colorado’s snowpack. So what does it mean for your water supply? (Colorado Sun)
In Colorado, 83% of the state’s water supply comes from surface water fed by winter snowpack and spring runoff. Colorado’s snowmelt also flows downstream to millions of other users in the Colorado River Basin. Having the most accurate snowpack measurement possible is vital for water agencies, which use the data to figure out how much ends up in home faucets and on farms for irrigation. The search for new, more accurate ways to measure snowpack is on. Read more
A boom year for Sierra Nevada snow (NASA)
After three years of busts, 2023 was a boom year for snow in the Sierra Nevada. Data provided by INSTAARs Noah Molotch, Leanne Lestak, and Kehan Yang provide a detailed picture of snowpack across the range and at different elevations, which helps the California Department of Water Resources and other water managers better forecast snowmelt in California.
