Snowmobile rider thrown off by hidden rocks

Dramatic footage has emerged of the moment a snowmobile rider hit a rock and was sent flying off in Tumbler Ridge BC, Canada earlier this month.

The video, captured by a helmet camera, shows him crash into obstacles hidden under the snowfall before rolling all the way down the hill - leaving his snowmobile on his side.

Thankfully the filmer escaped serious injury. He later wrote online: " I was climbing a mountain side after buddy went up the hill. I didnt go far enough around the rocks on hill and crashed into rock/tree base. Rolled down the mountain. The hill I climbed was an estimate 900 feet."
