Mkinvartsveri by Peter Schön.
Peter Schön: "This image was taken in April 2006 during a first-ski descent mission to iconic Mkinvartsveri (Kazbek, 5054 m) in the Georgian Caucasus. We sat out several days of intense storms, some of the strongest I have witnessed. The intense winds created massive snow plumes blowing off the summit. The photo arguably marked the start of photography career, as it found its way into exhibitions and magazines such as Alpinist."
