When you look a river in spring, you saw the ice pushing by the current. If the ice stop, it will create a dam... and it will inundate every think above the dam. In climbing, many people used the term clusterfuck when many party are stick between other.
As a debacle happen, or after a water fall, the ice flow can be so strong that it can destroy a bridge. It is also a situation that happen in climbing when a team try to pass other and place them in dangerous situation. Few years ago, a party was climbing half dome and try to pass an other by the right. The guy move a block that felt on his rope. The body was discover at the bottom of the cliff.
I think that when you climb, you most know the normal flow on a climb. For example, on standard route frankeinstein cliff, many party climb it by a warm day. If to be safe, only four party most be on the route at the same time, every one most respect that. Before, we call that measure of time the commitment rating.
As a forum, I thought that experience climber and guide most discuss what is the commitment rating and wrote it as it is in many guide book. As a climber, I wrote a blog to discuss more deeply the situation. You see the news at tv, but you read more detail in journal. So, I hope that people will understand that it is more a positive blog to the site than a competition between two forum.
