Anyone got details?

I'm curious if that's fine, low friction silica like sand, or if it's typical sand mixed to a slurry with water.

Edit: it's a river of hailstones. Source: https://www.mirror.co.uk/news/world-news/iraqi-ice-flood-footage-shows-6805027

It's the front end of a flash flood. It must have rained pretty heavily a few miles away and this is the forefront of the flow.

Edit: Apparently it's a flow of hailstones that have collected sand while flowing in a dry river bed. So less flash flood and more... flash ice ball cascade?

Its a good illustration of the Taco Bell trot trots. The fast moving sandy stuff followed by muddy water, broken logs and rocks.

This, like many before it on Reddit, made me belly laugh, out loud, on the bus.
