One thing to keep in mind is the game is set in the lake tahoe area.
there's alot of information on Wikipedia on the tribes that lived/live in the area, alot of the names of the items and patters on the basket come from those tribes.
I do think that in order to create the most lore friendly RP tribe one must dabble in paleo-Indian cultures a bit. Having aspects of many cultures in a tribe is something that really interests me. Similar to how the fallout franchise has created the various tribal cultures in the wasteland, I hope to create something of that caliber.
