I know this because blogger Steve Casimiro over at The Adventure Life did what we were too lazy to do and compiled a list of both websites and snow reports for all the ski resorts in the U.S.
Out of 481 total resorts, only a few have zero presence on the web, and
most offer snow reports. Unless you have a hankering for a particularly
obscure mom-and-pop operation, you can pop over to the page Steve so
generously compiled and figure out exactly what conditions are like
with one click.
I imagine this'll also be a fantastic resource for eccentric
billionaires, who can cruise for the best snow conditions in the
country, jump onto their private helicopter/hovercraft, and jet to the
resort of their choice each weekend. Lucky for us indigent peeps,
there's a good chance it'll be in our backyard.
