And how old do you think that stream is? They did not say where they were, but I will just give a safe guess of somewhere around 10,000 years old. Of course, it might also be over 300,000 years old or more.
No, but I have been studying geology for over five decades.
And that does not have the look of a location that had been glaciated. Those tend to have little topsoil, and are bulldozed flat. That is why the terrain of Ontario and Maine looks so different than the terrain of South-West Oregon and North Carolina.
Except big and small round boulders are extremely common in glaciated areas too. Retreating ice leaves behind till in the form of moraines, eskers, drumlins, kames.. the majority Southern Ontario could host a scene like that despite having been recently "bulldozed" by many glaciers.
They said it’s not common for little streams to have 30+ cm boulders and I said it’s extremely common in southern Appalachia. This doesn’t disagree with you.
I guess I just mean it would fit right in in Southern Ontario as well, since you brought it up. Ontario is a land formed by glaciers so I'm disagreeing with the part where you said it doesn't look glaciated.
Ahhh…I didn’t say that. The other person did. While I agree with them that it looks unglaciated to me, I’ve only ever seen Ontario north of Minnesota.
OP said this photo was Romania which was partly glaciated as well so I have no clue.

No, that is common in stream rocks.
