These riders in Norway were having a little competition to see who could get the furthest up the mountain before their snowmobilers couldn't go any further. Just like any other guys hanging out these days, they were filming their competition—then the mountain flipped the script on them and an avalanche came rolling down after them as they tried to flee.

The reports we've read say that all of the riders in the video made it out alive and are doing ok. We sure hope so. It's spring, the snow is melting, and avalanches are much more likely to happen this time of year. Extreme sports enthusiasts, please be careful out there! [Reddit]
