The timing and process of freeze-up is changing in Alaska. The changes are poorly understood, making it hard to plan for our winter activities and community safety on the ice. Your photos of river freeze-up can help! Please contribute photos of a river near you. Repeated photos of the same location are especially needed. 
You may contribute photos 3 different ways:
- Upload at
- Download the GLOBE Observer App to your phone and take photos using the landcover tool.
- Post a photo with a date and detailed location notes at
The Fresh Eyes on Ice Project is a partnership between University of Alaska Fairbanks, Tanana Chiefs Conference, NASA GLOBE Observer, and the National Weather Service Alaska Pacific River Forecast Center. Funding for the project comes from NSF Navigating the New Arctic program and NASA Citizen Science for Earth Systems Program.
