Good question! That’s the title of a story in a new online magazine from the Getty. Go read it and see — great photos, as you might expect!
The intro reminds me of my sister’s reaction to the Grand Canyon. Our mother woke us up very early and drove to get there as soon after dawn as she could (my mother’s not a natural early riser herself). My sister took one look into the Canyon and said something like “OK, it’s a big hole in the ground.” In her defense, she was 12.
Your sister was right. That’s what it is. But it is the most beautiful and inspiring “big hole in the ground” that I have ever seen.
