How wind moves and redistributes snow at Erciyes

Dry, light snow is easy material for wind to move. Above a certain speed, wind lifts surface grains and carries them downwind — which means the surface can change substantially without any new snow falling at all.

The dry continental snow at Erciyes is particularly susceptible. Damp, heavy snow bonds to the surface more readily; light snow at the same wind speed travels far more easily.

The result is that windward faces get scoured while leeward faces accumulate. Two slopes at the same elevation can therefore offer completely different skiing.

On windward ridges and open flats, snow is continuously removed. What remains is compressed, hard and sometimes icy: the air gaps between grains are reduced, so cover looks thin and skis firm.

These surfaces demand a well-maintained edge. A dull edge slides rather than grips on wind-packed snow, and control drops off noticeably.

Cover on these features can also be genuinely thin. Early and late in the season, wind-scoured ridges may not have enough snow over the ground beneath, whatever the overall depth figure says.

Where wind loses speed it drops what it is carrying: leeward slopes, hollows, and the ground behind any obstacle. Cover in these areas is markedly deeper than the surrounding terrain.

For a skier these zones are appealing, because this is where the soft, deep snow is. But deposition is uneven: depth can change substantially within a few metres.

That unevenness is what makes it risky in flat light. The transition from soft deposit to hard scoured surface is abrupt, and with poor visibility you do not see it coming.

The most insidious effect of wind is on visibility. Snow lifted off the ground cuts visibility as effectively as snow falling from the sky, so a day with no precipitation — even a sunny one — can have very poor visibility up high.

This is called blowing snow, and it does not appear as a separate line in most forecasts. The best proxy is wind speed combined with how dry the surface snow is.

The wide open terrain above the treeline at Erciyes amplifies it. On such a day, dropping elevation to pistes with reference points around them is the most sensible response.

What usually stops a chairlift is not average wind speed but sudden gusts. When the average looks acceptable while gusts are markedly higher, expect intermittent operation through the day.

Enclosed gondola cabins tolerate wind better than open chairs. At Erciyes that means the Lifos gondola at Hacılar and the Tekir gondola are the lines most likely to keep running.

Ottoman, the highest line at 3,346 m, is fully exposed and is usually among the first to be held. Whether any line is turning is published only by the resort.

A windy day is not automatically a lost day; it is a day that requires choosing terrain rather than defaulting to it. Leeward slopes offer both better snow and less exposure.

The morning after a strongly windy day is when the surface is at its most uneven, with the contrast between scoured and loaded areas at its sharpest. Grooming removes most of that on the pistes overnight, so staying on-piste that morning makes more sense than usual.

Above all, check the official lift status before you set off. Conditions can look fine from the valley while the lines you planned your day around are held.
