Volcanic field
Fort Selkirk is the northernmost active volcano in Canada. It is located in central Yukon near the junction of Yukon and Pelly rivers. The volcano consists of pyroclastic cones and lava flows.
Fort Selkirk volcano is located at the intersection of two prominent lineaments; one running east-west, denned by the Pelly River and the lower Yukon River, and the other running NW-SE, defined by the upper Yukon River.
Two types of eruptions have occurred at the volcano - eruption of fluid valley-filling lavas and explosive eruptions which created pyroclastic vents with viscous aa lava flows.
Valley-filling Eruptions
Wolverine Creek Sequence fills the Wolverine Creek are was probably erupted from a vent at the prominent lobe along the southeast contact of the Wolverine Sequence. A second vent may be located on the knoll southeast of Wootton's Cone.
Central vent Eruptions
Volcano Mountain is a pyroclastic cinder cone with three summit pit craters and thick blocky aa flows. The lack of vegetation means it may have erupted in the past few thousand years. Wootton's Cone (Ne Che Ddhawa) is a sub-glacial
pyroclastic cone which sits on the older Wolverine Creek Sequence lavas. Fort Selkirk Vent is located 4 km downstream from the junction of the Yukon and Pelly Rivers.
