400 year old arrow or dart from Tsitsutl glacier, B.C. Source: Keddie and Nelson: 2005.
In 1924, a land surveyor found an arrow at an elevation of 2,100 metres near Tsitsutl Peak in west-central British Columbia (map). The arrow made its way to the Royal BC Museum where it lay for over 80 years, until a timely inquiry and increased awareness of ice-patch archaeology stimulated a small research program. This research, initiated by RBCM curator Grant Keddie and reported in the Canadian Journal of Archaeology (Keddie and Nelson 2005), establishes that the arrow is about 400 years old.
