Numerous methods abound. Each has advantages and disadvantages. Reasons To Backup An Abseil There are a plethora of reasons to backup an abseil (and several not to do so). You might foresee a tricky descent, possibly involving untangling the ropes. Reasons Not To Backup An Abseil In other words you're 100% reliant on your brake hand. The descent is straightforward and/or short and the climber is experienced enough to judge the risks. Method's Of Backing Up An Abseil The method you use will be dependant on the conditions of each descent. Abseil Backups Involving Another Participant In this instance you want some from of backup and you have another participant ready to help. Fireman's Belay Very simple and fast given that someone is already on the ground (or bottom of the pitch), and available to hold the rope. Belay From Above Pretty obvious.
Simple One Tree Top-Rope « SAdkClimber Blog Matt W. asked for a pictorial step-by-step for a simple top-rope setup. Here, after a month or two, it finally is. Thank you for your patience, Matt. Equipment Used One Stout Tree, provided by M. Here we have the perfect scene for potential catastrophe: dirty, damp slab leading to a nice cliff. First, we’re going to fold our static line in half. This is the “End Side” This is the “Bend Side” We’re going to tie the End Side around the tree, using a bowline knot. Take the End Side and fold it around the tree, with plenty of extra line for tying our bowline knot. Make a ring or loop, near the tree, on the part of the rope opposite the ends, by grabbing it and twisting.IMPORTANT: the loop must be made so that the side running toward the Bend End lies UNDER the side wrapping around the tree. Starting from the ground and going up, poke the end side through this loop. Poke the end side back through the loop, going toward the ground this time. Pull the knot snug. Back up the knot. All good? Maybe.
Blog Posts from Joe Stock - Stock Alpine LLC The Northern Warfare Training Center is based at Fort Wainwright in Fairbanks. NWTC instructors teach field courses at the Black Rapids training site, in the Alaska Range off the Delta Highway. In early November I joined five NWTC instructors at the Matanuska Glacier for a four-day advanced ice climbing course. Since they have a solid foundation in ice climbing, our goal was tuning their instruction technique and their tuning their climbing technique. These guys are fun, have tons of experience and are keen to learn. I first instructed ice climbing on the Mat Glacier in 1999 while preparing for a 12-day trip to the Bagley Icefield. The Matanuska Glacier office hasn't changed in 15 years. We started the course from scratch, which means flat footing. To solidify our footwork we climbed near-vertical ice with no tools. Then we climbed with one tool. Spongy glacier ice climbing? We covered ice anchors. Working on transitions from belaying a second to descent by lowering and rappelling.
How to Rig a 2-Ring Retrievable Anchor - Canyoneering Tech Tips About tjones Tom is the progenitor of Tom's Utah Canyoneering Guide, Utah's premier canyoneering information resource, and Imlay Canyon Gear, America's #1 maker of canyoneering-specific gear. If he's not canyoneering, he's probably snuggled up with a good book. Ghosting Techniques - Rope Work 101 When using ghosting techniques it is best to have at least five experienced people in the group. I recommend that you follow these steps: Set up the retrievable anchor system and try several test pulls to make sure that it is secure and does not get hung up on rock, branches, or any other obstacle.Backup the anchor, preferably by a large obstacle nearby. If there is nothing else to anchor to, use human anchors, use two or three people to start with.Send the heaviest person down fist, if the anchor fails your backup anchor should catch the fall.If everything looks secure after the fist person down, send the next heaviest person down and repeat until the most experienced person (hopefully this person is one of the lighter people in the group) is the only one left.

Category:Riggings - ropewiki A rigging is a configuration of equipment that makes rope work such as rappelling and ascending possible, or the act of putting the equipment in that configuration. It could be as simple as tying the end of a rope around an anchor and throwing the rest of the rope down a cliff, or as complicated as a complex-compound mechanical advantage system intended to haul a patient up a guided rappel. A full list of riggings on this wiki may be found at the end of this page. Anchor ring systems Because most canyoneering routes are through trips rather than in-and-back trips, the group must be able to retrieve all of the equipment used to rig a rappel from the bottom of the rappel after the entire group has finished rappelling. Many additional riggings start with this setup and then add additional rigging to provide additional features. Dye Clan describes and compares a number of anchor ring systems. Fixed systems Retrievable systems (Ghosting) Some examples of retrievable systems are:
Guided rappel - ropewiki A guided rappel will be useful to allow rappelers overcome a dangerous hydraulic, a keeper hole or transfer a victim over a waterfall. Set blocked rope at top of drop to rappel down single lineRappel down and overcome the obstacleMake an anchor at the bottom of the drop to tie off the guide line (which will now also become the new rappel anchor)The blocked line the first person used for rappel is now the guide line. Tension it using any tension system (examples shown below)Throw down the rope bag to the person below (or zip line the rope bag down on the tensioned line), creating a second line from the top of the drop to the anchor at bottomGet people on guided rappel: Have them clip with a short tether directly to the tensioned guide lineHave them rappel on the loose, bag side of the rope (make sure the bag reaches the bottom anchor and is securely fastened to the bottom anchor first)Once everyone is done, release the guide line from the bottom anchorPull down the rope as usual Voodoo
