The activity of riding down snowy slopes on a sled, either for fun or transportation.
From Old Norse 'sleðr' meaning 'sled,' Germanic in origin, combining with the '-ing' suffix to create the present participle form describing the action itself.
Sledding is actually one of humanity's oldest winter activities—cultures from Scandinavia to Mongolia independently invented sleds because snow is slippery and gravity is free, making it the ultimate low-tech entertainment.
