When I was a young child, and I slid down a snow/ice covered hill, I called it sledding. In Shishmaref, the same activity is referred to as sliding. In fact, I’ve heard adults correct little kids if they call it sledding. (The Inupiaq word for slides down a hill is sisugaqtuq; although, I’ve never heard anyone use it.)
I think it’s because, in Shishmaref, “sled” means something very different from the thin plastic discs I grew up “sledding” on.
The picture above is a typical Shishmaref sled. The men around here make them. It is a very involved process that includes steaming the wood to get it into the right shape.
