Snow on the Course
Is snow "casual water"?
Snow can either be "casual water" or a "loose impediment"
at the option of the player.
Frost however is not "casual water" ot a "loose impediment" (Definitions "R&A Rules of Golf")
To obtain relief, under "casual water", the ball must be dropped within one club length of the nearest point of relief, not nearer the hole. If the ball is in a bunker it must be dropped in the bunker. (R&A Rule 25-1).
To obtain relief, under "loose impediment", the snow may be removed (R&A Rule 23-1)
Best of Luck with moving the snow or finding relief away from it !!!!
