Living on the Edge
Our adventure began with a 2- hour road trip to from Santa Fe to Socorro, New Mexico. Our destination was Box Canyon, 6.5 miles beyond Socorro. We got off the hi-way and drove on a dirt path to get to the bottom of the canyon. Jason lifted me out of the jeep and into my wheelchair. He turned me towards the cliff. It was more than a rock wall, it was a 13-A. Cliffs are rated by their difficulty to climb, with 1 being the easiest, 14 the most difficult. They are additionally rated A - C. A is not as difficult as C. Ratings help climbers decide which cliffs they could climb. This would be a very difficult climb.
Jason explained the procedures to me. He had custom made a harness for my wheelchair. Jason and his crew put a body harness on me as a backup in case the chair harness gave way. I was carried up a narrow trail to the base of 13A.
The ropes from my harness were fed through a carabiner secured to the top of the cliff. Nothing was left to chance. Every rope, every carabiner, every strap was checked and re-checked.
All the slack was taken out of the rope. I began my ascent. Every time the ropes were pulled from below, the pulley above would creak and groan under the strain. With each pull on the haul line I moved straight up and, for the briefest of moments, seemed to be weightless. As the rope lost its slack I regained my equilibrium and prepared for the next haul. It wasn’t long before I reached the peak. The wind whistled through my hair as I enjoyed the spectacular view over 120 feet above ground. I felt privileged to be sharing an experience known only to other climbers, people who have the same reverence for nature, danger, and the element of uncertainty ever present in this type of activity.
While dangling from the top of the cliff I remembered the words of Helen Keller, “Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a daring adventure or nothing.”
Jason and his crew used carabiners as pulleys to hoist me up the face of the cliff just as the Romans used cranes to lift heavy objects 2,000 years ago.
In the picture below, a man in a treadmill helps turn a giant wheel as part of this human-powered crane. Using simple pulleys, a person can lift an object much heavier than him or herself. Using several pulleys makes it even easier.
1. When my friends hoisted me up to the top of the cliff, they used a system very similar to using a pulley (or block and tackle) with the carabiner taking the place of the pulley. Can you think of places you mind find pulleys in and around your house?
2. If you were going to climb a cliff that was rated 4-B, would that be an easy or difficult climb?
3. What states border on New Mexico?
4. How many pulleys are used to lift the weight in the second picture?
The pictures below show 2 types of carabiners. The picture on the left shows how a carabiner is opened. The picture on the right shows carabiners used as keyrings. I included this picture to help give you an idea of the size of carabiners.
You may find pulleys in your curtain pulls. If you have a garage with an electric opener you will find a pulley there. If you live in an old house, there may be lead weights on a pulley system attached to your windows to help keep them open (they are hidden behind the wall). Some people have a pulley in their garage to lift engines out of cars. If you look very closely at some windbreakers, heavy jackets and even some tent fasteners, you may find pulleys there.
