Ice Miners in Yakutia. How much is a cubic meter of drinking ice

Mining of drinking ice in Yakutsk coldest city on the World. This is what I ve been wanting to see with my own eyes for a long time. And it happened quite by chance, when we were driving along the winter road of the Lena River (the same road made of the bluest ice), we met icebreakers, ice miners. I was lucky, because they have been preparing drinking ice in Yakutia for more than 20 years and they have something to tell.
