Native Alaskans, historically (7)
I believe the answer is:
eskimos
'native alaskans historically' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for eskimos that I've seen before include "The Inuit people" , "Is smoke made by Artic people ?" , "People, usu. now Inuits" , "Igloo dwellers" , "Northern dwellers" .)
