Alpine terrain above the altitude where trees can grow, typically open and wind-affected. It is a term used in mountain terrain and piste features.
Mountain terrain varies enormously between resorts and even between different parts of the same mountain. Above treeline is something you will encounter regularly when reading piste maps and resort guides. The gradient, aspect and altitude of the terrain all affect snow quality and difficulty. Resort grading systems (green, blue, red, black) help skiers identify suitable terrain.
Understanding above treeline helps you read the piste map and choose terrain that matches your ability. Always check local signage and conditions before venturing into unfamiliar areas.
