The
Taltheilei Shale Tradition is the archeological name of the material culture of a late prehistoric western-area subarctic people dated to the period of 750 BC to AD 1000. The Taltheilei Shale Tradition is named after the "Taltheilei Narrows" (
place of open water) of
Great Slave Lake. Taltheilei people were Proto-
Athapaskans.
