In autumn 2025, two ice streams formed on the northern wall of Pik Korona. The first ascent of the right stream (rated 5A in the Russian classification) was made by Aleksandr Parfyonov's team in early 2026. The first ascent of the left stream was made by Konstantin Markevich with Aleksey Pototskiy in the second half of March 2026. Further, according to Aleksey:

Last year was very hot in July. And as a result of this circumstance, two new routes formed on the northern wall of Pik Korona. The charm of these routes is that this year or next, such conditions may not happen, and these routes may not exist. But while they are there - we have to climb 😁 And we did. One route was climbed by Parfyonov with a partner in February, and the second one - Kostya Markevich and I last week.

Honest 5B and this is the coolest ice in the area. The icicle itself is 170 m of 87-degree lace cascade ice. And before that, there's another 30 meters of A3 ice climbing. The lower part is 450 m of gentle ice at 55-70 degrees.

People often ask about the weather in Ala-Archa, when the best season is, and when it's safe to ice climb. I've decided to put this information into a micro-article.

January

Stable weather, many sunny days, often calm. The temperature at Ratschek hut is -10 to -20°C with rare deviations from this range. However, there's only 2 hours of sunlight per day, not enough to warm up.

February

Almost like January, but towards the end of the month, stability is lost – March is approaching.

March

Very unstable weather. Stormy winds can last for 2 consecutive days, and fog can hang for 2 weeks. Heavy snowfalls are rare but possible. On good days, even in early March, it's sometimes possible to walk in a T-shirt when the sun is out. Daytime temperatures range from -10 to +5°C.

April

The same March winds, but it gets warmer.

May

One of the most popular routes to the Corona peak crest wall. It starts from the bergschrund, from which there are about 450 meters of even ice to the ridge. On the penultimate rope of the route, there is a small ice ridge, which is a bit more complicated than the main section of the route. The start of the route is 70-100 meters to the right of the https://summitx.info/en/routes/58844837/about route. In the Russian official classification, both these routes are considered variants of the same route.
