Radar has many uses: tracking planes, making sure you're not going too fast while driving, and, most importantly, for skiers and snowboarders: finding snow. Spread across the country, radars are a key part of tracking storms and allowing you to find new leads. The only problem? They're remote (the one in the video below was only accessible via a 15-mile snowmobile ride) and their beams can't cross mountains. But that's okay, because as meteorologist Joel Gratz explains, without radar… finding snow would be a little more difficult.
