... recultivation process begins in our mountain resorts. The aim is that our skiers were skiing on snow-covered meadows without rocks and on well-maintained pistes.
Adjustments on pistes are made based on consideration of the slope´s gradient, altitude, bedrock, ground stability, the nature and type of habitat. Such adjustments are made largely by hand and heavy machine equipment is used only for rough work. The surface of pistes is gently levelled, stones are gathered and are then put aside along with the remaining soil, creating so called humus soil horizon. They are used later, for example for building guttering, solidifying stream banks, flattening the terrain, or are just put to the roadside. Erosion cuts are also very important to drain water into the side green.
When the put off soil is layered on the sub-grade soil, the surface started to be covered with grass mixture and hay, and where steep slopes are found, hay is covered with fleece to protect layers from water. Subsequently grass is mowed, levelled in summer in order to protect contact points of skies, and for ski slopes to be covered with artificial snow as soon as possible. Above the forest, where the trees do not make nice scenery and snow is blown away from the pistes, snow barriers are used. Barriers, in addition to capturing the snow on the pistes are also used as demarcation of the pistes to protect anybody from falling into an abyss.
When the groomer passes through the snow it can cut about 10 cm of snow, which is not able to starve, so the bumps are created with breathtaking speed. Therefore groomers start maintaining slopes immediately after opening hours to provide solid snow for skiing in the morning. When the area is covered in more than 10 cm of snow at night, we adjust slopes of course in the morning before opening hours. There is often a dilemma: there is 30 cm of snow at the bottom of the slopes where the groomer could harm the slope, but several metres higher there is above 40 cm of snow, which would help… but a number of other factors have to be taken in consideration (type of snow, humidity, snow viscosity, number of skiers that ski through the slopes).
When you see a few inches of snow in the morning, it is not always possible to groom, because you just scratch the slope unnecessarily and what´s the worst, you create the lumps and it is very difficult to get rid of them. It's a little different on the glaciers (and higher located resorts in the Alps) where the amount of ice produces cold, which is able to make slopes to be starved within 10 minutes. And when the sun goes down behind a cloud, the bump you have blown open without problems on your previous ride, will throw you out in the air, because it has hardened.
Thank you. We hope that you learned something new about our work. It´ll be our pleasure to welcome you this winter that we also cannot wait. Here are some improvements waiting for impatient visitors in winter at Jasna. Some of them were implemented based on your suggestions.
