So its like A Horn of Bronze or any potential fictional works made in-universe? Neat.
A Horn of Bronze (and for that matter,
Land of Salmon and Totems, the other PNW TL here) could belong to a specific sub-version focusing on the Pacific Northwest. There's an obvious aesthetic with the wooden longhouses, longships, totem poles, geometric art, and salmon fishing. You could do the same for all the cultural regions of the Americas really. It's similar to how Lands of Ice and Mice deals with the Inuit.
Now what I'd love to see is expanding a concept like that to the whole sub-Arctic and basing the aesthetic and setting off of shared traits. Out of similar resources and climate plus cultural universals, there's a lot of convergent evolution present in architecture, art, diet, and even mythology. You'd have a PNW-esque civilisation, an Algonquian/Iroquoian-esque civilisation, a Jastorf/Hallstat/Northern European-esque civilisation, a Finnic-esque civilisation, a Proto-Slavic-esque civilisation, a Tungusic-esque civilisation, an Ainu/Jomon civilisation, etc., and maybe even something totally out there like a Tasmanian Aboriginal, Maori, or Chonos civilisation to represent the Southern Hemisphere. Basically groups with that similar aesthetic going on with all the wooden architecture. Think Kizhi Pogost in Karelia, stave churches in Norway, reconstructions of traditional villages in Southeastern Alaska or British Columbia, etc. or modern takes on this aesthetic like art illustrating scenes from the Kalevala or Slavic mythology or a bunch of folk metal album covers. Here's an example of the aesthetic, it's a modern take on traditional Slavic culture.
I'd also add new shared cultural traits, like a preference for bronze weapons and tools, and a different set of domesticates. Like there'd be exotic looking sheep and goats (Mountain goats? Bighorn sheep?) and instead of horses and cattle they'd have reindeer and moose. I'd think the reindeer would have different temperment than OTL so you could actually use them as cavalry but reindeer large enough to carry an adult male are still rare so cavalry are still limited. And plenty of "Viking" raids too, be it the Germanic-esque culture, the Haida-esque culture, etc. This is probably better for a fantasy setting so you could have all sorts of magic, spirits like haltija or kamui everywhere, and wandering heroic gods inspired by Raven, Väinämöinen, etc.
I don't know to call this.
Forestpunk maybe? Or
Totempunk (playing off the use of "totem" to refer to ancestral guardian spirits as well as totem poles)? I'd love to write something like this but my hands are full with too much other stuff to write and do. Plus I think this sort of setting is best enjoyed in the visual arts.
Olenpunk - From a TL where indigenous tribe of the regions surrounding OTL's Sea of Okhotsk down to far northern Korea developed into a fairly complex reindeer herding and berry-farming culture. Things start to get real hard once not only does Russia starts its eastwards conquest, but Jin Dynasty China sees an opportunity too. Battles in the muck of the taigas and between native shamanist and buddhist religions and orthodox christianity and islam ensue across the Far East, Manchuria, and inner Mongolia.
In other words, the wild west, but vodka-flavoured.
I'd love to see what the Sakha would do in settings like that. A "Meiji Sakha Khanate" should be mandatory for anyone who dares write that.
