BackgroundEffusive valley-filling eruptions
The lava flows of the Wolverine Creek Sequence fill the Wolverine Creek. They were probably erupted from a fissure vent at the prominent lobe located at the southeast contact of the Wolverine Sequence. A second vent may be located southeast of Wootton's Cone.
Construction of cinder cones
The filling of Wolverine Creek with basaltic lava was followed by the construction of 3 cinderr cones:
Wootton's Cone (Ne Che Ddhawa) is a sub-glacial pyroclastic cone overlying the older Wolverine Creek Sequence lavas. It is composed primarily of hyaloclastite tuffs, breccias, and pillow breccias, witnesses of the subglacial nature of its formation.
Fort Selkirk Vent is located 4 km downstream from the junction of the Yukon and Pelly Rivers.
Volcano Mountain is a cinder cone containing 3 summit craters and thick blocky aa lava flows spreading at its base. The lack of vegetation suggests a young age, probably only a few hundreds or thousands years.
