This is our last freeze-up video and first break-up video of the winter. As part of the Fresh Eyes on Ice project (http://fresheyesonice.org/) at University of Alaska Fairbanks we are documenting ice phenology of rivers across Alaska. This is our last of 2022 freeze-up videos and first of our 2023 break-up videos because the Copper never fully froze up this year in our camera view. Accordingly this one is a bit longer. Thanks to Wrangell St. Elias National Park and Preserve for hosting this camera and Upstream Learning's students and parents for participating in local ice observations.
