"Glacier looks like what it is"

It is the flow of water. The frozen flow of water. Ice is still a liquid just with a rather high viscosity.

It flows via internal shear stress (deformation), basal melting resulting in sliding and/or if resting on a soft bed - subglacial deformation.

Thank you for attending my TEDTalk.

Well, it flows because of gravity.

No, no.. he's got point. None of the other things happening would matter without the downward force to cause the flow. It would just be a block or a puddle if it didn't have the gravity to pull it down.

Isn’t ice, by definition, not still a liquid? It’s a solid, as in one of the three states of matter (solid, liquid, gas), no?

I consider myself extremely fortunate to have seen this in person. Alaska is something else.

Not even stuck. Most of them actually move but at a rate we can't notice by iust looking at them. There are even some of them that scratched the river/ocean floor while moving and startled sonic underwater detectors. I think you can find them on YT

Harding ice field! That hike was the highlight of my first Alaska trip!

Yep, that’s from up here in Alaska. Glaciers are frozen highways through the mountains.

It's always weird to see the name "fjord" on things that are too far from the sea to be fjords.

Huh, that waterfall is really slow. Must be buffering

It definitely is the flow of water.

I bet it was a lot bigger 25 years ago

It was!! The NPS have installed a sign indicating how much the glacier has melted in the past 100+ years and it's mind boggling to imagine the scale of it in the past years

Interesting to see such lush vegetation right next to it. The glaciers I'm used to are usually surrounded by a barren moraine that takes decades or longer to be colonised by plants.
