Behind the scenes at the ski resorts: Piste maintenance after the end of the season

18/12/2023 - SnowTrex

The season is over, the lifts are open. Summer is coming. What happens to the ski slopes now? SnowTrex asked someone who knows all about piste maintenance. Friedl Eberl is an authorised signatory and operations manager of the lifts in Hohe Salve/SkiWelt Wilder Kaiser – Brixental. He is responsible for the operation, maintenance and care of the mountain lifts and pistes in Hopfgarten-Itter-Kelchsau.

Snow groomers are mostly used at night.

Mr Eberl, what happens when the season is over?

On the first day after the official end of the ski season, we start dismantling the slopes straight away. Each lift removes the safety equipment, piste markings, barrier tape and impact mats in its area of responsibility. Anything and everything that doesn’t look good in the ski area has to be removed in spring. We do this work while there is still snow so that we can remove the material more easily with the piste machines. The material is then stored at the valley stations. The next step is the cleaning work after the snow has melted. Starting at the bottom, we tidy up the slopes. Every piece of dirt, every piece of paper that people leave behind has to be picked up.

Do guests leave a lot of rubbish behind?

I have to say that the amount of rubbish has decreased in recent years. The occasional pair of glasses, a ski pole, a key or wallet, that’s it. The problem is still the small things like tissues and cigarette butts. There’s quite a lot there.

What’s the strangest thing you’ve found on the piste so far?

I once went out in the snow groomer. It was early in the morning and snowing lightly. We saw something red lying in the middle of a beautiful piste. We got out and looked at it up close. It was a small pair of panties, and 20 metres further up was a bra. We wondered how lingerie could possibly end up in a place like this. We had a good chuckle. We save valuable finds such as passports, car keys or purses and keep a list of them.

Where do the gondolas actually park in summer?

Does every object have to be removed from the slopes?

Absolutely. We are responsible for keeping the entire ski area clean so that the areas can be used for farming in the summer. The mountain railways make sure that there is absolutely no dirt lying around so that the farmers can mow and cultivate the areas.

99 per cent of our pistes are used for agricultural purposes. All pistes are mown at the end of May and all areas are completely grazed until the last descent. The cattle are herded up and brought to the areas. It turns out that the farmers have a great advantage through our making snow on the slopes, as the snow takes longer to melt in spring and the grazing area remains wetter.

Why is snowmaking on the slopes an advantage?

The grass stays green and lush for longer. That is a serendipitous win-win for both us and the farmers. Alpine pasture farming involves gradual grazing. The cattle should first graze the grass next to the slopes, as it is less moist and therefore wilts more quickly. Then it is the turn of the longer lush grass on the slopes. The advantage is that the cattle always get fresh grass. Both sides benefit from this approach. It even goes so far that some farmers come to us and ask us: “Snow a little more so that we have fresh grass for the cattle for even longer in summer.”

In the past, farmers would first go to the Niederalm and then to the Hochalm, as the grass was still fresh there later. We achieve this effect here with our snowmaking system. The vegetation is practically delayed a little. This form of landscape management is a big issue for us. A good sward with healthy vegetation has the effect that we need less snow in autumn to achieve an optimal surface. There are also no stones, for example.

The perfect piste preparation requires many hours of track driving.

How much time is left for piste maintenance between seasons?

Skiing is open until April. The entire ski area has to be clean by mid-May. Everything has to be ready within a month. We can never rule out the possibility of a piste machine damaging something, i.e. causing damage to the slope. This damage must of course also be repaired by us.

What happens before the start of the winter season?

The cattle drive is at the end of September. As soon as the cattle have left, we can set everything up again. The summer season ends in mid-October and the winter season starts at the beginning of December. So again, we only have just over a month for this. Of course, the snow cannons also have to be set up again.

Where do the snow groomers spend the summer?

The snow groomers (aka ‘snow cats’ or ‘piste bashers’) are parked in garages on the slopes. Each machine needs its own parking space, so our twelve machines need twelve garages. That takes up a lot of space, but they can’t be parked outside, not only for visual reasons but also for technical reasons.

Where do the gondolas and chairlifts spend the summer?

On the modern lifts, the individual gondolas are taken off the rope every day and serviced if necessary. On the older lifts, the chairs remain on the rope. There aren’t many of the older chairlifts left in the SkiWelt anyway. In the case of older lifts, we consider on a case-by-case basis whether to leave the chairs on over the summer. In these cases, it’s really only the appearance on the mountain that counts. If it disturbs the landscape, the chairs come off. Many of our gondolas also run in summer. Basic maintenance must be carried out immediately after the season. The lifts that also run in summer undergo basic maintenance at the end of the season in spring and again before the start of the season in autumn. There are a lot of regulations to follow, even though we only have one month to do this. The lifts that only run in winter are then gradually serviced over the summer.

The gondolas remain on the cable as they are also used in summer

What do the lift workers and snow groomer drivers do in summer?

In winter, we have around 100 employees in Hopfgarten. Of these, 80 people are only with us in the three main months. Most of them are farmers and construction workers who can’t work on the building site in winter. They are all well-qualified workers. Lorry drivers move the snow groomers because they can drive the machines. As I said, we have twelve caterpillars for our area alone.

Do the drivers need a lot of expertise to prepare the pistes?

The snow groomer drivers have a tough job, it’s all night work. The trips take eight to nine hours. Over the last five years, cable winch technology has become established in piste preparation, as it delivers the best results. The snow is pushed up the piste, i.e. always from the bottom to the top. To do this, the piste machine is attached to a cable that is anchored at the top of the mountain. The cable is then tensioned up to 1,000 metres downwards and the vehicle is pulled upwards on the cable. This saves the machine a lot of energy. We can also prepare very steep slopes perfectly in this way. It is the most energy-efficient variant of piste preparation to date.

Are there any risks involved in grooming with cable technology?

The cable is tensioned approx. 1.70 metres above the ground. If your colleagues drive into it, it’s life-threatening. We don’t tension the cable immediately after the piste ends at 16:30, but if someone wants to ski down later in the twilight, the rules must be observed. We put up rotating lights and warning signs. Nevertheless, some people overlook or ignore our warnings and accidents do happen. We really have to be careful. Of course, no piste machines are in operation when the lift is running.

FAQ’s on piste maintenance

What happens to the slopes after the end of the season?

The dismantling of the pistes begins immediately after the end of the season: piste markings, impact mats, barrier tapes, etc. – everything is cleared away. As soon as the snow has melted, the ski area is also tidied up: all rubbish is collected so that the meadows can be mown and maintained in summer.

What can be found in the ski area after the snow melts?

In addition to the usual rubbish such as paper scraps and cigarette butts, the lift companies also frequently find glasses, ski poles, keys and wallets.

What happens to the slopes before the start of the season?

After the cattle drive, the area is prepared for skiing. All machines and materials such as snow cannons, impact mats, piste markings etc. are set up again.

Where do snow groomers spend the summer?

Snow groomers are kept in their own garages in summer.
