response: They also used a single long pole, or just a spear.
original_response: Yes, and early skiers actually used spears as ski poles.
history: Skiing is one of my favorite pasttimes. I wish I could do it more. Were you aware that skiing goes back almost 5,000 years? I wonder what they used for skiis back then. I'm not sure, but the word ski actually comes from skio. That is Old Norse for split piece of wood. Now that is pretty cool. So they named it after the piece of wood they originally used. They originally skied as an aid for travel, though now skiing is mostly a recreational activity. Oh ok, so it was created out of necessity.
knowledge: Early skiers used one long pole or spear.
