  • ski slopes are usually prepared mechanically by means of rollers, milling machines, snow blowers and other mechanically driven snow processing tools, which are attached to, and transported and driven by, snow groomers.
  • the SKUS Sudiss Commission for Accident Prevention on Snow Sports Valley Rides stipulates that all ski slopes marked in blue, red or black must be prepared within three days of a snowfall. An inexperienced alpine skier first learns to ski on blue marked (easy) ski slopes.
  • skier With increasing experience and correspondingly increasing skiing ability, over time he will be able to ski down slopes that are marked red (medium) and black (difficult). If a skier is looking for a further increase in skiing challenges, he often goes to fresh-snow terrain (also known as freeride terrain) outside of secured ski slopes or on yellow-marked ski slopes that are neither groomed nor controlled. In unsecured terrain, however, the skier is exposed to considerably greater dangers in the form of avalanches, hidden stones or tree stumps, among other things, than on the secured ski slopes. Skiing outside of secured ski slopes is therefore reserved only for very experienced skiers or groups of skiers accompanied by a ski instructor.

  • a method for producing a ski slope according to the invention is characterized in that the first slope section is regularly groomed from time to time in a manner known for the preparation of ski slopes, while the second slope section is left unprepared for at least one week.

  • the second, unprepared slope section is preferably formed in an area of the ski slope which was prepared in previous years and which is known to be heavily used by skiers.

Such a mogul slope increases skiing fun for experienced skiers.
  • the area ratio of the first to the second slope section at the beginning of a season section is changed depending on the number of skiers on the ski slope expected for this season section. For example, at the beginning of a season section with a skier frequency estimated to be low, the second pislen section was enlarged in area and the first pislen section was reduced in area. As a result, the effort required for grooming the slopes can be reduced by reducing the total area of the ski slope to be groomed. If section boundary marking means mark the boundary between the first and the second slope section, for this purpose only the section boundary marking means need to be moved into the previously prepared first slope section and then the entire enlarged second slope section must be left unprepared.
  • the second slope section can be reduced in area and the area of the first slope enlarged in order to create enough space for a large number of inexperienced skiers on the prepared slope section. If section boundary marking means mark the boundary between the first and the second slope section, for this purpose only the section boundary marking means have to be moved into the previously unprepared second slope section and then the entire enlarged first slope section has to be prepared.
  • a further possibility for enlarging the area of the unprepared second slope section consists in that only the edge marking means marking the slope edge of this unprepared slope section are displaced outwards from the center of the slope, so that not only the second slope section but also the ski slope as a whole is widened. In this case, the effort for grooming the slopes remains the same because the total area of the groomed slope sections is not changed.

Abstract

L'invention concerne une piste de ski (10, 110, 210) construite sur un terrain en pente et comprenant deux bords latéraux (11, 12, 212) qui sont marqués par des moyens de marquage (11.1, 11.2, 11.3, 12.1, 12.2, 12.3). Les bords (11, 12, 212) et l'inclinaison de la piste définissent un sens de piste (13.1, 13.2, 13.3). Entre les deux bords de piste (11, 12, 212) marqués, une première section de piste (20, 120) est conçue comme section préparée (20, 120) et une deuxième section de piste (30, 130, 230) comme section volontairement non préparée (30, 130, 230), la deuxième section (30, 130, 230) juxtaposant la première section de piste (20, 120) par rapport au sens de piste (13.1, 13.2, 13.3). Cette piste (10, 110, 210) permet, même à des skieurs entraînés, de skier de manière exigeante mais sans danger.
