Here is an update from Ken Siems of the Pestovo Golf and Yacht Club in Moscow. The first picture is from April 8 and the second one is from April 12, 2013. He has removed snow cover from some of the key areas on the golf course, but is expecting snow cover to last in May. So far, the grass has been pretty healthy under the snow, with little snow mold (he treated for snow mold before the first snow).
This is one of the latest snow covers that I am familiar with. It will be very interesting to see how the course emerges from the winter. Ken will continue to keep us informed as the snow melts.
