re: Yes.
I visited Yellowstone back in the early 80’s (Before the big fires). I was just there a couple of day (to short, but then, I could spend years in that place).
I remember standing somewhere in the middle of the park out in a grassy field. There were buffalo and elk around. There was a ranger telling us about how Yellowstone sits in a huge caldera. He pointed around the horizons 360 degrees and said “All of those mountains you see are really the rim of the caldera. Yes, it became apparent. It did look like we were in a huge crater. What a massive eruption it must have been.
