Rubble is an area of collapsed ice. A Large area of rubble can last for several days, a scenario of collapsed building sites one after the other. These sections are best avoided by climbing ice pinnacles and scouting for flat areas on the horizon. It is a common beginners mistake to keep a straight line and go into rubble headfirst. Travel alongside of the area until you find flatter ice.
Sometimes, however, rubble trouble cannot be avoided and you'll have to get ready to rumble. Patience is the name of the game and not to despair. Although rubble can seem endless and is no fun for camp; it will end. It's just one of those obstacles testing out how badly you want the pole.
