CLIMBING GLOSSARY

 

A

 

Abseil - (pronounced AB-sail) When a climber descends from the top of a wall or rock by sliding down a fixed rope using a figure eight. It is another word for rappel that is typically used outside the United States.

 

Accessory cord - strong and very low stretch cord that is typically a smaller diameter than climbing rope with a range of different uses.  

 

Active protection - A piece of climbing equipment that has moving parts and sometimes springs.

 

Aid climbing - The opposite of free climbing. It is a type of climbing that uses bolts and pitons rather than a climber’s hands and feet on the rock itself to ascend. This was used almost exclusively before proper climbing shoes started becoming more popular.

 

Anchor - anything that holds the rope and climber to the rock. This could be a bolt with a bolt hanger, a protection piece on the climb, or a sling.

 

Approach - The trail to the start point of a climb.

 

Arete - A wall feature that looks like a vertical corner. For example the corner of a building.

 

Armbar - a climbing move used for climbing large cracks where the palm is placed on one side and the elbow is placed on the other.

 

ATC (Air Traffic Controller) - See Belay Device.

 

Auto-lock - the spring-loaded mechanism on some carabiner gates that locks the gate once it is closed.

 

B

 

Backclip - During lead climbing when the climber places the rope through a quickdraw backwards.  This is very dangerous because during a fall the rope can unclip itself.

 

Backstep - A climbing move where the climber uses the outside edge of the foot to stand on a hold.

    

Barn door - When a climber is unbalanced while climbing and their own body weight causes them to swing away from the rock face.

    

Belay - The act of controlling the rope for the climber and locking off the rope during a fall. In top-roping this involves pulling in extra slack in the rope as the climber ascends; in lead climbing this involves feeding rope through the ATC/belay device for the climber to clip into quickdraws as they climb.

 

Belay Loop - The loop in front of the harness to which the belayer clips the belay device and carabiner.

 

Belay/Rappel Device - A device used by someone on the ground or anchored in place [the belayer] to manage the rope while someone else climbs.  It helps to stop the rope if the climber falls and makes for a smoother descent when rappelling.

    

Belayer - Someone who manages the climber’s rope to ensure the climber may ascend freely and lock off the rope in the event of a fall.  A Belayer is required when top-roping or lead climbing.

 

Bent-gate carabiner - A carabiner used in sport-climbing that has a bent gate to allow for a larger opening for clipping in a rope.

 

Beta - Advice on how to do a climb usually by someone that has done it already.  If you watch someone send a climb, you are getting beta.

 

Bight - A bend or fold in a rope; A loop of rope where each end does not cross.  Ex: A bight of rope is placed into a belay device when setting up before a climb.

Biner - Short for "carabiner".

 

Bivouac - A temporary camp on a rock face during a multi-day climb.

 

Bivy - Short for “bivouac”.

    

Body belay - A technique for belaying without a belay device where the rope is passed around the belayer’s body.  It should only be used when a belay device is not available as it is not the most effective way to belay and can be painful to the belayer.

Bottleneck - A crack that gradually gets smaller.

 

Bouldering - A type of climbing that is done usually within 20ft of the ground without a rope. Bouldering started as a way to practice technique and has evolved into a different form of climbing. When bouldering outside, it is especially important to have your own crash pads, helmet and spotter. In a gym, there is significantly more padding and near ideal falling conditions.

 

Bowline - A knot used to form a loop in a rope that does not slip. It is commonly used in rescue situations.

Face Climbing - A type of climbing that uses features like edges, slopers that can only be found on a slab of rock as opposed to crack climbing which requires counter pressure and using the crack to climb.

 

Fall Factor - A way to determine the amount of force exerted on a rope in a fall. Divide fall length by the amount of rope. If a climber falls 3 meters and there are 50 meters of rope between them and the belayer the fall factor is smaller than if there were only 10 meters of rope in play.

Free climb - What we typically think of as rock climbing at this time. When a climber ascends a wall with only the use of hands and feet where the rope is only present to catch the climber in the event of a fall. Free climbing is the opposite of aid climbing.

    

Free rappel - A descent down a rock face where the rappeller is only sliding down a rope rather than walking backwards down a rock face.

    

Free solo - Climbing without a rope or protection of any kind. It is very dangerous and any mistakes can result in severe injury or death. 

    

Friction - The force exerted from one surface coming into contact with another. In climbing, it is a style where contact between the hands and soles of the climbing shoes are used instead of edges and cracks.

H

 

Half rope - A technique where two smaller ropes are used when lead climbing. One end of each rope is tied to the climber’s belay loop and the other end is controlled by the belayer using an ATC. One rope is used for protection points on the left and the other is on the right. The benefit of this system is that the rope does not zig-zag across the rock as a climber ascends.

 

Hand Crack - A gap in a rock face that is thicker than a finger, but smaller than a fist.

 

Hand jam - A climbing move similar to a fingerlock or Fist Jam, where the climber crams their hand into a crack in such a way as to hold themselves in place.

Hanging belay - a belaying position where there is not a suitable place for the belayer to stand and therefore must be suspended by an anchor from the rock instead.

 

Harness - A high strength nylon belt system that wraps around a climber’s waist and legs. It is used to attach a climber to the end of a climbing or repelling rope.  A harness is essential for a safe climbing experience.

 

Headpoint - Rehearsing a climbing route with a top rope before lead climbing it.  Headpointing is usually done when there is a large gap between protection points on the climb and a fall between them could lead to a serious injury.

 

Heel hook - A climbing move where the climber uses their heel to hold onto the rock face.

 

Highball bouldering - A bouldering route that goes above 15-20ft making a fall very dangerous.

 

Hot aches - An intense “pins and needles” feeling when blood starts to recirculate through cold hands or feet.  If you have ever put a leg to sleep, it is a similar and more intense sensation.

J

 

Jam - A climbing move where the climber uses a body part, usually a finger, hand or fist to create a wedge shape inside of a crack to hold them against the rock face.

 

Jug - Same as a “Bucket”, a climbing hold that is easy to hold onto.  It would be similar to grasping the lip of a large bowl.

 

K

L

 

Last - A wood or plastic tool shaped like a foot used to build a climbing shoe.

 

Layback - A climbing move where the climber pushes against the rock with their feet and pulls with their arms to create the counter pressure and friction necessary to hold them onto the wall.  It is used a lot when climbing a crack that is in a dihedral formation.

 

Leader - The climber that starts a lead climb.  In sport climbing, the leader sets the quickdraws and in trad climbing they set all of the protection.

 

Leg loops - The pieces of a harness that wrap around a climber’s upper legs. In a premade harness, they are usually attached to the waist belt.  If a climber uses a “Swiss Seat” harness, it is very important to make sure the leg loops do not cross between the legs or there could be serious injury in a fall.

 

Lockoff - A climbing move where the climber is holding onto the wall face with their arm or arms fully bent.  It is the same as when doing a pullup; the lock off is when the person is at the highest position in the exercise.

 

Lower - Typically in a gym, this is where the belayer slowly lets rope back out of the belay device to bring the climber safely back to the ground after a fall, multiple attempts, or completion.

 

 

M

 

Mantel - A climbing move where the climber uses the palm of their hand to push downward and lift their body high enough to get their foot to their hand; similar to climbing out a deep hole.

 

Mono - A climbing hold that can only fit one finger.

 

Multi-pitch - A type of climb that is longer than the rope being used.  During a multi-pitch climb, once the lead climber gets to the end of the rope or a good stopping point, they will then belay the second climber who will then climb to them and switch back to belaying or continue passed and become the lead climber.

 

Munter hitch - A knot used with a carabiner that can be used to belay a climber. It is a good knot to know in case a climber drops or loses their belay device.

 

 

N

Nut tool - a long and flat piece of metal that is hooked at one end to help a climber remove passive protection from a climb.

 

O

 

Off-width - A crack with a width that is between the size of a fist and a person’s body.  Typical jams cannot be used because of its width.

    

On sight - When a climber completes a climb on their first try without any prior knowledge or mistakes on the way up.  In climbing competitions all climbers are kept in a separate room away from the climbing area to ensure every climber does an on-sight climb.

Slingshot rand - A piece of rubber on a climbing shoe that completely wraps around the foot to prevent the shoe from stretching and the climber’s foot from sliding around in the shoe.

 

Slipper - A climbing shoe that does not have laces or straps and can be slipped on and off easily.

 

Sloper - A climbing hold that is large and very smooth. It is gripped using the friction of an open hand against the rock.

 

Shock Load - The load exerted on an anchor after a fall.

Slack - A command made by the climber to tell the belayer to let out some rope. Usually this is done to get rope around something it is caught on or to give the climber some flexiblity.

 

Smear - A method of griping the rock with the friction from the bottom of a climbing shoe against the rock.

 

Solo - To climb alone without protection.

 

Speed Climbing - A type of climbing usually done in a gym, where two climbers ascend identical routes and they are timed. Speed climbing is also performed outdoors where the goal is to climb a route as quickly as possible.

 

Sport climbing - Rock climbing where all of the protection has already been placed and all that is needed are quickdraws and a rope.  Sport climbing is mostly done indoors, but there are places where expansion anchors have been installed to sport climb outdoors.

 

SRENE - An acronym for checking the qualities of a good climbing anchor. It stands for Solid, Redundant, Equalized and No Extension.

 

Static - 1. A type of rope that does not stretch and is used mostly for rappelling and rescue.  Using a static rope when climbing would be dangerous because it cannot absorb the impact from the fall. 2. A form of climbing where the moves are slow and deliberate and there isn’t any swinging or jumping from hold to hold.

    

Stem - A climbing technique where upward movement is achieved by applying pressure against opposite walls; usually in a chimney or a dihedral.

 

Sticht plate - One of the original belay devices.  It acts similarly to an ATC, but is no longer used due to the effectiveness of ATCs and Gri-gris.

 

Stick Clip - A pole that is used to hook the first quickdraw with the climbing rope already threaded through it on a sport climb. This done so that the climber is on belay when they first start.

 

Stopper Knot - The knot tied at the end of a rope to keep it from coming out of the belay device while climbing.

Toe Hook - A climbing move where the top of the foot is used to wrap around and hold onto the rock. When buying shoes, it is important to note the amount of rubber on the top of the shoes for toe hooking.

 

Top roping - A type of climbing where the rope is looped through anchors at the top of a climb where one end is attached to the climber and the other is attached to the belayer. The benefit of top roping over lead climbing is that the climber does not need to worry about clipping in and if they fall, they will not fall very far.

 

Traditional or "trad" climbing - A type of rock climbing where the climber must place protection and clip in as they ascend a route as opposed to sport climbing where the protection has already been installed.  The protection is then removed by the second climber that climbs the route. This is the most advanced form of climbing with a rope.

 

Traverse - To move horizontally across a rock face rather than vertically.  A traverse close to the ground can serve as a good way to warm up safely.

 

Tube chock - A chock that is made from a cylindrical piece of aluminum that is used in very wide crack where a regular chock may be too small. Some tube chocks are expandable to fit in different shaped cracks.
