A terrain park is a dedicated area within a ski resort, built and maintained for freestyle skiing and snowboarding, featuring constructed obstacles such as jumps (kickers), rails, boxes, and other features for performing tricks. Parks are graded by difficulty (small to extra-large features) and follow a 'Smart Style' code of conduct, since the jumps and features carry real injury risk and demand etiquette and progression.
Breakable crust is a snow condition in which a hard crust forms on top of softer snow but isn't strong enough to support a skier's weight — so it breaks unpredictably as you move across it, trapping skis and legs and making turns extremely difficult. Formed by sun, wind, rain, or melt-refreeze creating a crust over weaker snow beneath, breakable crust is one of the most challenging and frustrating surfaces to ski, demanding cautious technique or avoidance.
Crud is a catch-all term for difficult, heavy, and variable snow conditions — including chopped-up tracked powder, wind-affected snow, heavy wet snow, and partially refrozen crust — that are challenging and tiring to ski because the surface is uneven and unpredictable. Skiing crud well requires a strong, balanced, adaptable stance, active legs to absorb the inconsistencies, and committing to turns rather than getting bucked around by the changing snow.
Corn snow is a smooth, forgiving, granular snow surface that forms in spring through repeated daily melt-freeze cycles, which turn the snowpack into rounded, loosely bonded grains resembling corn kernels. Skied at the right moment — after the overnight frozen surface softens but before it turns to slush — corn offers some of the most enjoyable spring skiing, and timing is everything.
A groomer is a ski run that has been mechanically smoothed and packed by grooming machines (snowcats) into an even, consistent surface, often leaving a corrugated 'corduroy' texture. Groomers provide a predictable, smooth surface ideal for carving, learning, and cruising, making them the bread-and-butter terrain at ski resorts. The term refers both to the groomed run itself and, sometimes, to the grooming machine that creates it.
Off-piste refers to skiing or snowboarding on ungroomed, unmarked snow outside the prepared, patrolled pistes (runs) of a resort. It offers untracked powder, fresh challenges, and escape from crowds, but the terrain is not groomed, marked, controlled for avalanches, or patrolled — so it carries significantly greater risk, including avalanches, hidden hazards, and tree wells.
A piste is a marked and maintained (usually groomed) ski run at a resort, designated for skiing and snowboarding. The term distinguishes prepared, patrolled terrain ('on-piste') from ungroomed, unpatrolled snow ('off-piste'). Pistes are graded by difficulty using a color-coded system that varies by region, helping skiers choose runs that match their ability.
Powder is fresh, light, dry, uncompacted snow — the soft, fluffy snow that skiers and snowboarders prize above all other conditions. Its low density lets skis and boards float through it, creating a smooth, surfy, almost weightless sensation. The driest, deepest powder (often called 'champagne powder') is especially coveted. Powder requires adapted technique and, in the backcountry, heightened avalanche awareness.
The Barryvox is a well-known line of avalanche transceivers (beacons) made by Mammut, used to locate companions buried in an avalanche. Like all modern transceivers, it transmits a standard signal while worn and switches to a digital search mode to home in on a buried beacon. The Barryvox is a brand example of the essential avalanche beacon — one part of the mandatory beacon-shovel-probe rescue system for backcountry travel.
A tree well is a void or area of loose, deep, unconsolidated snow that forms around the base of a tree, hidden beneath the branches, in deep-snow conditions. A skier or rider who falls into one — often headfirst — can become trapped and suffocate, a danger known as snow immersion suffocation (SIS). Tree wells are a serious, underappreciated hazard of skiing in deep snow and trees.
