Not a fan of Frank Herbert's Dune novels?
Sorry, was too busy trying to unearth the term for sand being dislodged and tumbling/sliding/going down en masse, possibly burying somebody.
This doesn't lend itself to DuckDuckGoing.
However, I have discovered that when sandboarding (a real activity) or sand sledding (also a real activity), they've special kit to use.

Now that I think on it, I'm a bit surprised that they're putting in so much effort into sand when it seems unlikely to be a common obstacle. If snow sleds can't be used as sand sleds, would there be much crossover with sand and ice traction data?
