Microplastics low and high in Alaska | Alaska Science Forum

Two University of Alaska Fairbanks students head to Denali as they search for microplastics in the snow that covers the 20,310-foot mountain. One of them, Matthew Crisafi-Lurtsema, has been sending back satellite texts, one every day since they flew from Talkeetna to the Kahiltna Glacier in Denali on May 8, 2024.

Since May 17, he and Roger Jaramillo have been steadily climbing, collecting snow samples along the way. When they return, they will examine the melted snow for the presence of microplastics, which appear to be present everywhere on Earth.
