That's right, snurfing, with an 'n'. Snurf boards, or Snurfers, created in 1965 by Sherman Poppen in Muskegon, Michigan, are what many argue to be the predecessors to modern snowboards. Although snowboarding history is dominated by men, the beginnings of the sport actually started with Poppen's 11 year-old daughter who was standing on her sled riding it down a hill. I couldn't find any images of girls snurfing on snow, but I did find an image of this girl shredding sand on a Snurfer!
