Makah, Quileute, Chinook/Chinookan
I don't have time right now to add bits on the Makah, into the Nuu-cha-nulth section as a subsubsection, the Quileute (who have absorbed the surviving Chemakuans from what is now Clallam/Twana turf); the Chinooks are usually held to be the southern ""pole"" of the Northwest Coast cultures; not sure why the Tillamooks aren't.....but the Chinook should probably be on here....  
PS I made a redirect Northwest Coast culture which directs here....guess I'll do the same for Northwest Coast cultures (plural).  "
