The Houston Rock Climbing Meetup Message Board › Accidents in North American mountaineering
Many accidents occur when a climber rappels off the end of the rope and when a belayer lets the end of the rope go through the belay! these are preventable accidents.
Tie a knot into each end of the rope whenever you rappel or belay a climber, even if you think everything is OK. Safety is achieved by good habits.
At Enchanted Rock many of the routes are over 1/2 rope length and you cannot be lowered off of a single rope. Tell your climber when the half way mark passes your belay. If your rope is not marked - Mark it! Read the guide book and note which routes are more than 1/2 your rope length. 1/2 of a 50 meter rope is about 80 feet. 1/2 of a 60 meter rope is about 100 feet. All ropes are not the same length.
If you are a beginner belayer ask for a back up belay until you are sure you know how to belay properly and safely.
Read the American Alpine Club Accidents book. The stories in there will help you.
