Things You Might Not Know: Glaciers Don't Go Backwards

Glaciologists will find this video obvious. Everyone else... well, maybe I slept through a bit of sixth-grade geography, but I didn't know this, and I reckon I should have done.

A glacier is basically a slow moving frozen river. Of course it can't flow backwards. Gravity continues to work even below the freezing point.

More like a slow avalanche.

First time I ever heard glacier pronounced that way.

"Glassier"?

Glassier than what?

Well, cardboard's out.

Wow, I had no idea people though glaciers retreating meant the ice was actually going uphill. It's hard to understand how anybody could think that if they considered it for more than 30 seconds.

Yes, glaciers are like rivers, the ice plastically deforms and flows around obstacles. If anyone wants to see some great footage of this sort of thing, look up Chasing Ice
