The air that arrives.
The Altai sits deep inside the continent, far from any warm sea. We describe the winter air that reaches it as continental: it has travelled a long way over land out of Siberia and carries little moisture by the time it arrives. When that air is lifted by the range, it cools and drops what water it holds as snow. The result is a snowfall made from a dry air mass, not from a maritime front loaded with wet vapour.
Orographic lift does the rest. We use the term for air that is forced up over a ridge and cools as it rises; the higher it goes, the more of its small water content it gives up as snow. Because the starting air is already dry, the flakes are light and the settled layer keeps air between its grains. We would call this a structural property of the place, not a lucky season.
Dry to the touch.
Dry snow behaves differently under a ski and in a hand. We find it does not ball up or pack into a wet clump; it stays loose, squeaks underfoot in the cold, and shakes off a jacket rather than soaking through. The snow is cold, and it stays cold.
There is a trade we rarely see written down. Dry, light snow is easier to ski on but easier for the wind to move, so an exposed crest can be scoured while a sheltered hollow keeps its powder. We read the mountain in terms of where that snow has been kept, not simply where it fell.
What dry asks of gear.
Cold dry air is hard on skin and on equipment in quiet ways. We plan for lips and cheeks to chap, for hands to stiffen faster than people expect, and for any exposed metal to stay cold to the touch. Wax choice shifts toward colder grades, and a wet-weather shell is less useful than a windproof one. None of this is dramatic; it is a set of small adjustments that make a long day comfortable.
We also pace the day differently. Dry cold does not announce itself the way damp cold does, so groups can stay out longer than is wise and only notice the chill when they stop. We build in indoor breaks and watch the light rather than the clock. Treating the snow as dry is not a slogan about quality; it is a practical instruction about what to wear, how to wax, and when to come in.
