As someone who loves geography and snow I'm always looking new snowfall maps. Knowing the local variations of snowfall of not only the most recent storm but also the storm a few weeks or even a month prior can have a huge impact on trail conditions. I found this cool map that shows historical snowfall data over the U.S. Take a quick look at the help by clicking on the questions mark on the upper right side to learn the different features. You can search by date, date range or the RSI snowstorms. RSI snowstorms is the Regional Snowfall Index which is a way the use to rank storm severity. Enjoy!
