Ski Area Terminology, Slang, and Lingo

  • Used almost industry wide.
  • These terms are unique to monitoring ski areas. Lift terminology included is only that which is heard on the radio and has been simplified as much as possible. Most avalanche terminology is not included due the complexity of snow physics. Most avalanche terminology is only understood by those who have taken extensive training.
AED Automatic External Defibrillator
Air Jumping off the snow.
Alpine Refers to skiing done at developed ski areas on groomed slopes using skis equipped with bindings in which the entire boot is locked down on the ski. Also known as downhill skiing.
Anti-rollback A mechanical system, which prevents the weight of passengers from making the lift roll backwards in case the engine or gearbox fails.
APU Auxiliary Power Unit. A backup power system to run lifts in the event of a power failure.
Avalanche Beacon A small device that transmits short bursts of low power RF energy and is typically hung around a skier's neck. While skiing all members of a party lock the device into the transmit mode. If an avalanche occurs and someone is caught under the surface, rescuers switch to the receive mode. Using both direction and distance a person can locate a transmitting beacon under the snow.
Avie Avalanche
Beeper Avalanche beacon.
Boilerplate A hard ice pack snow surface that will not allow snowboard and ski edges to carve turns.
Boo Bamboo sticks. Used to hold hand charge explosives for avalanche triggering, and for many other uses such as holding up fences, marking hazards, placing signs, etc.
Bombing Skiing or riding a snowboard straight downhill recklessly and out of control.
Bowl A steep wide run, usually higher on both sides.
Box A feature in a terrain park that is like a rail, but wider and easier to negotiate.
Bull Wheel The large diameter sheave (pulley) at the ends of lift, one of which is powered (usually the lower called a drive bull wheel) and one which may be a tension sheave or bull wheel [adding the proper amount of tension to the rope (cable)], or may be just a return for the rope (a fixed return bull wheel). People who do not off-load the chair when they are supposed to are referred to as "going around the bull wheel".
Bump Moving ski patrol personnel from one station to another to provide variety or to cover an area when ski patrollers there are tied up working a significant injury.
Bump(s) Mogul(s). See "MOGUL"
Bunny An inexperienced female skier who is usually more interested in being seen than skiing.
Bunny Hill or Slope A nearly flat run for beginners.
Burrito A waterproof blanket/tarp which is folded into a rescue sled. The burrito may contain some or all of the following items: first aid kit, splints, backboard, oxygen, or an AED.
Cable See "WIRE ROPE"
Carve, Carving Turning with the edge of the snowboard or skis well dug into the snow surface and producing a stable, smooth turn without significant skidding or side slipping.
Champagne Powder The lightest, driest snow that is such that it is impossible to make a snowball from it.
Chowder Powder chopped up by snowboard and ski tracks.
Chute A steep ski run narrowed by bands of rocks or trees. Quite often the rims of the chute are higher than the run.
Circuit, bypass A circuit that partially or entirely circumvents monitoring and remote signal inputs of a malfunctioning operating circuit to allow operation of the system under specific conditions.
Circuit, control power The control power circuit is a normally a de-energized circuit. When energized this circuit provides power to the operating control circuit.
Circuit(s), operating control When energized these circuits provide power to all electrical control functions which start, stop, run, and control speed for the lift. If it is de-energized, the lift system will stop or remain at rest.
Corn (snow) A spring type condition where snowflakes have consolidated into pellets. Warm temperatures, freeze/thaw cycles and grooming contribute to this condition.
Cornice Develops at the top of a ridge or cliff on the lee side and overhangs the slope below. Snow laden heavy wind is the cause.
Couloir A narrow chute with rock walls on the sides.
Counterweight A weight used to maintain tension in the rope or a moving part.
Cross-country Skiing Uses relatively narrow, light skis, and light boots (usually leather), equipped with a binding that allows for heel lift. A forward kick and glide motion, which is very much like walking, is facilitated, and travel over flat, uphill, and downhill terrain is possible.
Crown The uphill edge of an avalanche where an overlying slab of snow has cracked and slid downhill.
Crud Wet, heavy, icy, cut up, mashed potato type snow that is hard to turn in.
Crust A frozen, surface layer on top of loose snow.
Death Cookie Compact, icy, chunks of snow often develop on a cats track and can be thrown off the cat’s route of travel. If it is not run over on subsequent passes of the cat, and broken up by the tiller, it will remain on the snow surface. Whether this happens on a downhill slope or on a groomed cross-country ski trail, when a ski hits this chunk, the resulting loss of control earns this object its name.
Deropement When a wire rope leaves its intended position in the groove of a sheave or saddle.
Detachable A lift where the chair or gondola car detaches from the rope by means of an automatic clamp. Enables slow loading and unloading at the terminals, while running the lift at a high speed.
Diagonal Stride The traditional form of cross-country skiing where one ski and the opposite hand and pole are moved forward simultaneously, weight is placed on the ski and kicked backwards while the pole is thrust to the rear, providing a forward pushing force. As the pushed ski moves to the rear, the opposite unweighted ski glides forward, while the opposite hand and pole are lifted up and forward. As the opposite ski moves forward, both skis glide, thus the diagonal stride is often called "kick and glide". Once the opposite ski is fully moved forward, the process is then completed for the other side of the body. The tip of the front ski and tail of the back ski form a diagonal line, thus the name of the technique.
Drive The electronic circuitry that controls the amount of voltage sent to the primary motor of the lift and controls its speed. It is also connected to all of the lift’s safety devices, which shuts down the lift automatically if a problem occurs on the line or at the terminals.
Drive Terminal Houses the motor gearbox, auxiliary engine, and drive and safety circuitry. It can either be on top or at the bottom of a lift ("top drive", "bottom drive"). Top drive is a bit more energy efficient, but requires the expense of providing electrical service to the top of the lift, which is costly.
Ego Snow Either groomed "packed powder" or corn snow that holds the edge of a ski very well with little effort. A skier will ski better than in other snow conditions.
Fall Line A line drawn down a slope in the direction of its maximum steepness.
First Aid Refusal Skier or rider who declines to have first aid or an evaluation done.
Freshies Annoying slang for new powder snow fallen on a slope, or transported there by the wind from non-groomed areas.
Gapers Skiers and boarders who stop to watch others and in so doing make it difficult to travel down the run.
Gearbox The lift’s transmission, which transfers power from the motor to the bull wheel at the drive terminal.
Gill Net Refers to the orange plastic fence which is placed to channel skiers and riders, slow them down, or to catch them or their equipment at the bottom of a slope, protecting those in line or in base facility areas.
Goods Untracked powder, often found in the ungroomed tree areas.
Granular Snow consists of large, course crystals similar to rock salt.
Gnar (Gnarly) Extremely challenging snow and/or weather conditions.
Grip Attaches the chair or car to the rope. They can be fixed or detachable.
Half Pipe See "PIPE."
Hand Work Work done on terrain park features that is very precise or is in an area where snow cats and groomers cannot access.
Hardpack Firm, almost icy snow
Haul Rope See "WIRE ROPE"
Heimo’s A Poma lift in the Canyon Lodge area. Named after long term director of lift maintenance and construction at Mammoth Mountain Ski Area, Heimo Ladinig.
Jib (ing) Skiing or riding a snowboard on a non-snow surface, usually in a terrain park.
Kick Turn Turning skis, one at a time, 180 degrees while standing in the same place.
Lift Used here to refer to both chair lifts and gondolas.
Liftie Ski lift operator.
Manky Rotten snow. i.e. a layer of snow that is no longer cohesive. It is sometimes used to describe the smell that polypropylene long underwear gives off when after a day on the slopes.
Manual Reset Switch Used to start the lift after it stops, due to a fault, and must be activated by the lift operator.
Magic Carpet A brand name for a surface lift that is similar to a conveyor belt. Guests step into the surface, which is a continuous surface. Typically used in children’s instruction areas and located on very gentle slopes.
Magic Wand Refers to the safety device, which is triggered by people who remain on the chair after passing the unloading ramp. When triggered it stops the lift as most chair lifts are not designed or built for people to ride downhill.
Maze The area in which the guests gather waiting to get on a lift. Optimizes lift loading by packing people large numbers of people into a relatively small area. More commonly known as a lift line.
Mogul Bumps on a ski hill are formed when many skiers make turns, throwing loose snow up on the side of each turn. As additional skiers follow the tracks of the previous skier, these deposits eventually harden into a series of fairly evenly spaced, steep bumps, which make skiing a little more difficult. Grooming equipment smoothes these off at night, and they are reformed the next day. Some steep runs are left with moguls, for those who like the challenge of the bumps.
Nordic Refers to cross-country skiing.
Out of Bounds Outside the patrolled boundary of a ski area.
Over (his/her) Head Indicates that a skier or rider has found himself or herself on a ski trail that is too steep or hard packed for the individual’s skill level to handle.
Over Speed Device An electric or mechanical device that automatically detects lift speed in excess of that intended by the designer or operator.
Packer Bar Mounted aft of the tiller across the rear of a snow cat. On the outside it resembles a metal culvert, but with parallel ridges and it turns as the cat moves forward, compacting the snow loosened by the tiller, using its own weight. The ridges form the "corduroy" appearance of freshly groomed snow.
Pieps A brand of avalanche beacon. See "AVALANCHE BEACON."
Pinhead Slang for a cross country or telemark skier. Refers to the three pin binding that used to be the standard on all cross country skis. See "THREE PINNER."
Pipe Half pipe in a terrain park, shaped just like a half of a pipe. Skiers and snowboarders then ride or ski up and down the sides while gradually traveling downhill.
Piste A French word referring to a groomed surface, packed snow or on a designated ski run or slope.
Piston Bully A brand of snow cat and groomer.
Poaching Skiing in an area that is outside the patrolled boundary of a ski area. In many areas may be prohibited by state law.
Poma A type of ski lift where the skier is pulled by a platter placed between the legs that is spring mounted to a wire rope.
Poodle PSIA ski and snowboard instructors. They are supervised by "head poodles."
Poodle Turns Showy demonstration ("show dog") turns made by PSIA Instructors sometimes when they are not teaching.
Posse The people a person usually skis or snowboards with.
Pow Annoying slang for powder snow. Also, even more annoyingly, referred to as "pow, pow." Powder snow has a low moisture content and thus is light and fluffy.
PSIA Professional Ski Instructors of America. Among other functions certifies teaching methods, qualifications of instructors, and provides training curriculum.
Quiver The skis and boards a person owns.
Rake Comprised of a long, metal handle and a "head" with "groomer teeth" that rake snow and can also move small amounts for grooming in areas that cannot be reached by a groomer or need precise, detailed grooming.
Rail Made out of metal and raised above the snow surface for skiers and snowboarders to slide down.
Rag Doll A person who has fallen and is limply sliding or tumbling down the slope, presumably because they are unconscious.
Randonee (Ran-doe-ney) Refers to skis or skiing with skis that are, or almost are, downhill or alpine in design. The heel portion of the binding can be released for cross country travel and locked down for downhill skiing. Also known as "Alpine Touring." A common joke among telemarkers is that "Randonee" is a French word meaning "can’t Telemark".
Rider Snowboarder.
Rope See "WIRE ROPE". Very few "rope tows" exist at ski areas anymore.
Rope Tow A type of ski lift where a loop of manila rope is strung between two large horizontal wheels, one of which is powered. The skier grabs the rope and is pulled up slope while skiing.
RPD Rope Position Detector. A safety device, which ensures the rope, is properly aligned. It is essentially a metal detector, which can sense very small (but out of specifications) movements in the rope.
RPD Fault When the wire rope is out of alignment the control station of the lift will indicate this.
Runaway A loose ski or snowboard traveling downhill.
Safety Gate A device that will automatically stop a lift when tripped by a passenger’s weight, contact, or passage. Is usually a light beam or fiberglass wand. Keeps the passenger from going all the way "around the bull wheel".
Scissoring Getting the tips of the skies crossed with edge to edge contact. In other words a disaster.
SCR Silicone Controlled Rectifier. Converts the commercial AC (alternating current) for use by a DC (direct current) motor that provides power for the lift.
Shaped Ski Modern skis with a pronounced side cut or narrowing near the bindings. These are the easiest skis to turn.
Sheaves Pulleys or wheels grooved for rope. Weight bearing and guidance sheaves are most noticeable on lift towers, where some can make a distinctive noise. They are lined with a special type of rubber when the sheave wheel supports or depresses the rope.
Shredder An expert snowboarder.
Sierra Cement Heavy, moist snowfall that often falls in the central Sierra.
Shot, Cut, and Cleared Indicates that ski patrol personnel have used explosives on a slope, ski cut it, and the slope is ready for grooming, maintenance personnel, and/or guests. Ski cutting consists of long, slope wide traverses, in which the patroller jumps up and down on their skis to place a force in the snowpack and releasing any potential avalanches. "Cut and cleared" refers to avalanche evaluation and control without the use of explosives.
Sitzmark Divot or depression left in the snow when a skier falls.
Skating A method of cross-country skiing used primarily for racing that developed in the late 1970’s. The motion of the skis resembles ice-skating. Shorter, stiffer skis, stiffer boots, and much longer poles are used than those used in light touring skiing .
Skating Lane A smooth, flat, groomed area, adjacent to the twin track grooming used for diagonal stride skiing.
Ski Cut Ski patrol employees use this technique after explosives (artillery or hand charges) to make sure the slope is stable enough to allow for public ski use. Long, traverse type turns are used while the patroller jumps up and down on the snow with their skis and thus introducing downward forces into the snowpack.
Skier A person using skis.
Skinny Skis Cross-country skis, which are used for touring.
Slab A cohesive layer of snow within the snowpack. This layer may not bond with other layers of snow and may slide (avalanche) if the weight of additional snow layers is added by subsequent storms are added or a force, such as the weight and movement of a skier, hiker, snowmobile or snowcat is added. Slabs will often slide when artillery shells or hand thrown explosives introduce force into the pack. This is done so that the slope will not slide while the public is skiing.
Sled A plastic sled designed for carrying an injured person in a prone position, with or without a backboard. Towed behind a ski patroller using two handles at the end of poles that are attached to the top of the sled, resembling a tow bar. These handles can be chained together; enabling the patroller to place the sled in front on steep slopes, hands free, where sidestepping, or handing the sled to another down slope patroller, may be necessary. The bottom of the sled has fins, 3-4 inches in depth, enabling the sled to be controlled.
Slider A skier who falls on a slope of sufficient steepness and does not stop immediately or shortly after the fall.
Snow Gun The device that mixes water and compressed air to make snow and direct it to where it is needed.
Snowplow(ing) Pushing skis into a V shape, with the tips narrow and the tails wide and rotating the ankles inwardly. This forces the inner edge of the skis to push into the snow harder. This is a beginning skier’s best method for controlling speed and stopping. Is an effective technique for both cross-country and downhill skiing.
Spork A combination of a scooper and a rake. Used to hand groom features in a terrain park.
Spring Conditions Snow is exposed to warm temperatures and cold nights where it melts and refreezes.
Steeps Double black diamond or steeper runs or slopes.
Sticks Skis, sometimes called "planks."
Telemarking A turn used by cross-country skiers when skiing down slope. This turn provides stability for cross-country skiers who are using a binding where the heel does not lock down. A Telemark turn is somewhat difficult to complete using light touring gear, due to the flexibility of the skis and the low cut boots. Advanced Telemarking occurs on the steepest slopes both in the backcountry and at developed ski areas. Often the boots are plastic and are well up the calf of the leg. The skis are often as wide as downhill or alpine skis. Note: not to be confused with "Telemarketing."
Terrain Park An area where obstacles or features are built from snow or non-snow surfaces for skiers or snowboard riders to slide across are provided. Includes Such things as jumps, rails, boxes, half-pipes and even the tops of small buildings.
Three Pinner A person using cross-country skis. Refers to the 3-pin binding where the toe of the boot has 3 holes that fit over 3 bins on the binding, to provide additional grip. This term is used in spite of the variety of bindings available for cross country skiing, including cable bindings (mostly used for backcountry skiing), the "NNN" or New Nordic Norm" (Normal) binding where a rod on the front of the boot clips into a spring tensioned portion of the binding, and specialized Telemark bindings.
Tiller A round cylinder mounted across and at the rear of a snow cat, equipped with Rota-tiller type prongs. The cylinder is hydraulically driven by power from the cat’s engine and independently controlled (both speed and height) by the driver. The tiller de-compacts the snow surface by breaking the snow into small, loose particles. See "PACKER BAR."
Toboggan Injured skiers used to be carried down the hill on these. Because they are so difficult to control, plastic sleds are now being used. See "SLED"
Transition The sloped, downhill side of a ski jump.
Traversing Skiing perpendicular to the fall line or downhill direction of a slope without turning. Kick turns are done after crossing the width of the slope. Often done by skiers that are on slopes too steep for their skill level or comfort.
Tree Well The unconsolidated snow underneath the foliage of trees, adjacent to the trunk. These can trap skiers who fall into them after skiing too close to trees.
White Room Deep and very dry powder snow.
Wire Rope Commonly known as a cable, but actually consists of lengths of wire twisted around a core to form strands. These strands are then twisted around a core in a rope like fashion to form a "wire rope".
Yard Sale When a skier or rider falls and loses equipment, such as released skis, poles, gloves, hat, goggles, sunglasses, etc., and the equipment slides down the slope.
