Crossposting from my TL, A Horn of Bronze.
Here is the Pacific Northwest and adjacent regions after the dawn of the Copper Age (c. 700 AD), specifically around 800 AD. A great earthquake and volcanic eruption are soon to shake the region. I have kept the legend separate.
1 - Thule culture - Muskox herders branching into reindeer pastoralism. Prefer to be left alone, but will trade whale products and the prized muskox fur qiviu to their southern neighbours. Currently migrating into North Asia and along the High Arctic coast.
2 - Kinngait culture - The last "Paleo-Inuit" culture, in the process of being displaced by the technologically superior Thule
3 - Yup'ik peoples - Relatives of the Thule culture, mainly reindeer pastoralists with no muskox. Constantly at war with the interior Dena peoples who have displaced them in much of their range.
4 - Guteikh peoples - Fishing and whaling peoples with marginal agriculture and reindeer herding. Increasingly competitive with the Ringitsu
5 - Post-Tachiri culture Dena - The origin area of pastoralism, agriculture, and metalworking in Fusania. Weaker in recent centuries due to the Late Antique Little Ice Age, but still quite powerful due to long-distance trade.
6 - Far Northwest cultures - Ringitsu, Khaida, Tsusha, and other coastal groups. Innovators of agriculture and whaling in Fusania, as well as many cultural traditions. Expert mariners and shipbuilders, and very warlike due to lack of good land. Especially fond of jade from the interior
7 - Interior Dena cultures - Influenced by the Tachiri culture Dena, but also by their Salishan and other southerly neighbours. Known as expert reindeer breeders and miners, and becoming quite known for their exports of gold, silver, copper, and jade. Especially fond of eulachon oil from the coast.
8. Wakashan cultures - Masterful whalers and coastal raiders, similar to the Far Northwest but culturally and religiously distinct. Highly skilled at textile arts and raising said crops as well as shipbuilding. In desperate need of land.
9. Post-Irikyaku culture peoples - Whulchomic, Salishan, Namal, Amim, Aipakhpam, and their relatives. An incipient agricultural civilisation (and center of plant domestication) and the economic heart of Fusania.
10 - Southern coastal peoples - Isolated by the mountains and their diversity of languages and dominated by various Dena peoples, with a culture similar to the Irikyaku peoples. Under pressure by Wakashan raiders who are eyeing their land.
11 - Southern mountain peoples - Dena and Amorera pastoralists under pressure from expanding agricultural civilisations. Frequent raiders of their neighbours.
12 - Southern plateau peoples - Dena and Maguraku people in the highlands, with other peoples in the lowlands, mostly pastoralist peoples. Quickly adopting the mountain goat traded from the north and developing a skill for mining.
13 - Kuskuskai peoples - Light agriculturalists under the rule of pastoralist Dena from the mountains. Slowly being enroached upon by the Tsupnitpelu, relatives of the Aipakhpam, pushed from the mountains by the Dena.
14 - Eastern plateau peoples - Uereppu, Tsupnitpelu, and some Dena peoples, pastoralist groups living in the hills. Pushed upon by northerly Dena groups and the expansion of agriculture, but also increasingly encultured by the Aipakhpam.
15 - South Fusanian cultures - Acorn gatherers and small-scale societies coming into a state of rapid change due to influx from the north.
16 - Plains cultures and others - Bison hunters and small-scale farmers who often trade across the mountains, most prominently the Ktanakha and Plains Salish, pushed onto the Plains by the Dena. Some Dena influence.
A - Nuklukayet [Nukurugawa] - Declined from its height but still a prominent village and religious site. It's revival is soon to come once the Medieval Warm Period arrives in this region.
B - Tagatili [Tachiri] - Another important village of the Dena--an archaeological culture will later be named after this place (the Tachiri culture) thanks to the rich finds from the early era of reindeer pastoralism.
C - Yutluhitl - A prominent town of Wakashi Island on a sound later named after it. A center of the whaling industry and all Atkh [Attsu] culture, and a center of Coastmen raiders preying on other Wakashans, Whulchomic peoples, the Namaru, and groups further south
D - Tlat'sap - At the mouth of the mighty Imaru River, the local Namaru people hold a key interface between the interior and the coast and the wealth it brings. Raiders can only harass the town, and it's Namaru rivals have no hope to defeat it's local influence. Yet geology and the ambition of humans has yet to come into play...
E - Katlamat [Katorimatsu] - An upriver rival of Tlat'sap, seeking to control the trade at the mouth of the Imaru. Tlat'sap has managed to hold off all attempts from Katlamat, but the increasing aggression of the Coastmen and mother nature may turn the tide in their favour
F - Wayam - An ancient trading center on the Imaru based on its rich fishing grounds and perhaps the first "city" of Fusania. A key point of the spread of the Irikyaku culture, a horticulturalist (and later agriculturalist) culture based on aquaculture and reindeer pastoralism. In this era, Wayam's earthworks, wooden palaces, and copper working has already established it as a place of immeasurable wealth. The Wayampam, an Aihamu people, live in the area.
G - Chemna - Like Wayam, a town of the Aihamu people established at a key fishing and trading site on the Imaru expanding thanks to its earthworks. The nobility of Chemna are increasingly jealous of Wayam's prosperity.
H - Shonitkwu - On another key fishing site of the Imaru, various Salishan peoples gather here to make a northern equivalent of Wayam. Influenced strongly by the Dena, but also southern peoples.
