What the record says

NCEI’s account, from the sources it cites.

Lava flow overran village. Several people who had dug pits for shelter died of "poison smoke". (reference #9675, 1412)

The eruption of Tseax cone is the only eruption in Canada for which legends of First Nations people have been verified. The Nisga'a (Tsimshian people) tell of a prolonged period of disruption by the volcano, including the destruction of their village on the Nass River and the death of some people (reportedly 2000) from "poisonous smoke" (Reference #12845, p. 223). (reference #12844) Note: the death of 2000 has not been cited elsewhere.
