#Ice is solid, right?
Well, not really. As it turns out, ice is actually relatively soft-- especially compared to, say, granite. It's also made up of water, so it's pretty heavy (one cubic foot of ice weighs almost 60 pounds). So the ice in a #glacier , which can be hundreds of yards thick, exerts a tremendous amount of force. Together with gravity, this relentless force deforms the soft(ish) ice over time and causes it to flow, more like a very thick liquid than a solid. The fastest glaciers can flow 10 miles in a year!
This convergence of three unnamed glaciers northwest of Mount Iliamna in @lakeclarknps is a great example of flowing ice in action.
