Hear the Otherworldly Sounds of Skating on Thin Ice | National Geographic

  • Published on:  2/9/2018
  • This small lake outside Stockholm, Sweden, emits otherworldly sounds as Mårten Ajne skates over its precariously thin, black ice. “Wild ice skating,” or “Nordic skating,” is both an art and a science. A skater seeks out the thinnest, most pristine black ice possible—both for its smoothness, and for its high-pitched, laser-like sounds.

    Black ice is recently frozen, and can be as thin as 2 inches and still support the weight of a skater. Like a dome or arch, the support comes from the sides rather than the top, and the water underneath prevents the ice from breaking. But, experience and careful advance planning are key. Factors including temperature, atmospheric conditions, and even satellite images of the Earth’s surface are considered. It’s complicated, but appealing to mathematicians like Ajne. Even with preparation, there’s a risk of falling in… So it’s best done in groups, for safety.

    So as you push off from the shore
    Won't you turn your head once more
    And make your peace with everyone?
    For those who choose to stay
    Will live just one more day
    To do the things they should have done.
    And as you cross the wilderness
    Spinning in your emptiness:
    You feel you have to pray.
    Looking for a sign
    that the universal mind
    has written you into the passion play.
