Recent investigations in the southern part of Haida Gwaii (Queen Charl
otte Islands, B.C.) demonstrate that this area was occupied prior to 9
000 RCYBP. Archaeological excavation and paleoecological analysis of t
wo sites on Arrow Creek and paleoenvironmental analysis of two sedimen
t cores collected from adjacent Matheson Inlet show that the sites wer
e occupied during a time of rapid sea level change. The oldest archaeo
logical remains at these sites date to shortly before 9200 RCYBP and t
he youngest to 5650 RCYBP.
