snow-how
Snow-how, a portmanteau of snow and know-how, is the knowledge and skill utilized during snow and inclement weather.
"Right. So these European settlers, who were total ding-dongs, came in the dead of winter, with zero snow-how. These underprepared vacationers turned to eating each other to survive. Eventually, though, they realized they were surrounded by scores of edible fish and wildlife." ~ Nick Offerman as Beef Tobin
