map of NA in the mid-11th century (~1080?) AD in a tl i've been plotting for a couple months. yellow areas denote areas of significant development of large cities (think altepetl-size, 20,000-100,000 max)
most of these names aren't final as i don't really have the time to re-transliterate every endonym
also this map took me like 3 weeks to make lol
important stuff:
-2 major centers of extensive urbanization: Toltec empire in Mexico and Tovaangar in SoCal, Ohlone Bay Miwok might count too
-linguistic differences: algic languages never spread past the Rockies, Iroquoian (ittl Ahowkwean) languages form majority of languages spoken east of the Great Plains. the Old Copper Complex is still relevant at this time, so you have copper goods being traded
-an Ahohwkwean group, the Cayoqesaunee occupy OTL's Cahokia and continue the mound-building tradition
-they're not on this map because i don't have much information on them but the Dorset culture, the peoples occupying eastern arctic Canada before the Inuit (whom i refer to as Tuniit which is a possibly anachronistic Inuit exonym) is still alive and kicking in northern Quebec and Wisconsin. similarly, Inuit groups extend much farther south, the southernmost occupying central Idaho
-major areas of cultural exchange: mexican kingdoms from the Naayarite to the Ch'orti', super-Southeastern Ceremonial Complex extending from Texas to Montreal, in the west the Tongva, Pomo, Wintun, Yakima all have a strong trading network. pueblo people in Oasisamerica are mostly doing their own thing. super-SECC and unnamed western complex are separated by the Great Plains and Rockies and mostly unaware of each other, but trade from the Toltec snakes its way up both civilizations, directly or indirectly
a lot of these names are probably anachronistic, so if you see anything weird tell me
