Brain Teaser Question that I can't answer?

A man is traveling and he comes to a canyon. The canyon is wide and deep. The only implement you have is a pole that is too short to help you cross. Your destination is on the other side. Those you are trying to join are standing on the other side. You can't turn back because the path you were traveling is now void of light. The light shines into the future. HOW DO YOU GET ACROSS TO THE OTHER SIDE?
