Thanks, ti-lo, and sorry. I made the change because of a post on mastodon that pointed to https://umap.openstreetmap.de/en/map/meteor-craters_94040#6/35.470/-107.325
which shows Upheaval Dome and a couple others, but Barringer (probably the most famous North American crater) is nearly invisible, and when I looked in iD, I didn't see any tagging as a meteor crater (because I didn't know there was a relation; now I know I needed to scroll down to the bottom in iD).

I'll move the added info to the relation. Just to be clear (because I still don't understand this very well): it's the Tourist Attraction feature where I should be adding it, right? That's where iD takes me if I click on the relation.
