Join NASA’s Community Snow Observations (CSO) program and the February Snow Chase!

The Community Snow Observations network is a community science effort that engages winter recreators in making snow measurements around the world. The Appalachian Mountain Club is joining CSO to help improve snow cover models and expand snow depths measurements in Northeast Mountain Landscapes. We need your help to measure snow depths in mountain regions, in places where we can’t cover!

Measuring snow depth takes only a few minutes out of your winter adventure. You'll become part of a growing community of observers and can learn more about the snowpack and its variability in the areas you frequent. Your measurements will help scientists improve snow cover estimates for avalanche safety, flood predictions, agriculture, and ecosystem science.

Please visit the CSO web site below to learn about the program, how to make measurements, and download the Mountain Hub App. You will need a measuring device (avalanche probe or ruler), a smart phone, and the free Mountain Hub App to participate.

Join the Feb Snow Chase and be entered into a drawing for a Backcountry Access backpack! There is only one rule and it’s simple: Head out in the backcountry and measure undisturbed snow at locations greater than 100 m (300 ft) apart. Tag your photos #febsnowchase to be featured throughout the contest.
