Geological summary

The basaltic Tseax River cinder cones (Aiyansh volcano) at the southern end of the Stikine volcanic belt have been the site of some of the youngest volcanic eruptions in Canada.

From Wikipedia

Tseax Cone is a small volcano in the Nass Ranges of the Hazelton Mountains in northwestern British Columbia, Canada. It has an elevation of 609 metres and lies within an east–west valley through which a tributary of the Tseax River flows. The volcano consists of two nested structures and was the source of four lava flows that descended into neighbouring valleys. A secondary eruptive centre lies just north of Tseax Cone on the opposite side of Melita Lake. It probably formed simultaneously with Tseax Cone, but the timing of volcanism at the two eruptive centres is not precisely known; both were formed by volcanic activity sometime in the last 800 years.
