Adventure tours on glaciers Zailiskiy Ala-Tau.

“I owe my success at that time to my guide Ryskul Dzhilkaidarov. You should have seen with what confidence he led us in dangerous places, past gaping cracks in the firn, along slippery icy slopes. By the right of the first explorer who completed the described path, I consider it fair to perpetuate the memory of my guide Ryskul Dzhilkaidarov by calling the valley in the upper reaches of the Issyk River in front of the pass glacier - the Ryskul Valley.”

Sergey Evgenievich Dmitriev (1861 – 1931).
