What happens when ice age glacier encounters tall mountain ranges? It gets "stuck" there, and it digs....

exactly, your illustration make it more clear

still interesting how ice "digs" lakes but we clearly
know they can carve out mountains, fjords are the best example

The bottom of ice age glacier sinks into the ground. Then as the glacier expands, it "grabs" the loose stuff and moves it. It digs straight down to the bedrock.

The two ice ages of today, one 1-2 million years old, the other 40, shown at current sea level with the ice removed...

^^^ proof Antarctic and South America were attached when they broke off from Africa 120+ million years ago.... and only broke apart 20 or so million years ago...

The glaciers dig along fault lines because that's where the bedrock is weak.

Glaciation is one of a number of processes that lead to the formation of lakes.

I mean it's a real cool topic millions of years in the making before we were around

it shapes what we have today

I've always been interested in science and history
so much to learn, it would take a lifetime

wonder if anybody can explain the great lakes though
5 at different depths, that is an interesting part

Most likely explained by different bedrock and the different glaciers that carved the individual lakes.

I thought you claimed you were taking geology classes.

I guess they didn't stick. Or you were lying again.

That is rather complex. But mostly failed continental rifting and 540 million year old basalt.
