This card arrived at the same time with the other Kazakhstan postcard and is also from Assel. Thank you!
This card shows Butakovskoye Gorge near Almaty city. There are high mountains, big waterfalls and even some wild animals there. This is what Assel told me of the place, I couldn't find any other info about it.
The stamp is from a set of 4 stamps issued in 2007, representing Olympic Champions from Kazakhstan. This one shows Vladimir Smirnov.
