Ah, the Saint Hannes cross, or sankthanskors in Sweden, or hannunvaakuna in Finland. It's not so much related to campgrounds, but to mark sightseeing spots in general.
No, it's used for "ancient monument", fornminne. It might be a early modern ruin or something that isn't ancient in some scientific sense but still is a place of historical or archaeological interest, while properly old remains, at least pre-reformatory ones, i.e. older than early 1500s, are often marked with a futhark 'r'/'ᚱ'.
It's used throughout much of Northern Europe as a more general sign for places of interest.
E.g. in Norway the sign is specifically described in regulations as referring to a "severdighet", literally something like "a seeworthy thing" but generally translated to "attraction". It's specifically regulated to mean that [1], rather than fornminne/ancient monument.
In Norway, you can for example find it used for the Holmenkollen ski jump, which is hardly an ancient monument [2].
If I had to guess, I'd guess Henry Dreyfuss's Symbol Sourcebook. It was published in 1972, and it seems plausibly the sort of book someone like Susan Kate might have had to hand in the early '80s. https://www.societyofsigns.com/projects/symbol-sourcebook
Symbol Sourcebook would’ve been my first guess, too, but I just glanced through my copy (7th printing, 1977) and didn’t see the ⌘ symbol. The closest thing in the Graphic Form Section is a symbol for “Atomic d orbital,” but it’s clearly not the same one that inspired Susan Kare.

Campgrounds have a normal descriptive “tent” symbol road sign in Sweden https://korkortonline.se/en/theory/road-signs/direction-sign...
More like, a place "worth seeing".
⇒ the article likely is wrong by adding “in a campground”, but it doesn’t say it means campground; it’s ‘only’ its title that does so.

I'm so surprised the button comes from that.

Unicode does not quite cover it because it lacks context and meaning of combined codepoints.
