Everything about Volcano Mountain totally explained
Volcano Mountain is an
active cinder cone in central
Yukon Territory,
Canada, located a short distance north of
Fort Selkirk, near the confluence of the
Pelly and
Yukon Rivers. Volcano Mountain is called
Nelrúna in the
Northern Tutchone language.
Geology
Volcano Mountain is the youngest volcano in the
Fort Selkirk Volcanic Field and one of the youngest in the northern section of the
Northern Cordilleran Volcanic Province. The lava at Volcano Mountain is called
olivine nephelinite, which is a very uncommon type of lava. This type of lava is believed to have come from much deeper inside the
Earth than the
basaltic lava. The last eruption from Volcano Mountain produced young nephelinitic
lava flows that remain unvegetated and appear to be only a few hundred years old. However, dating of sediments in lake impounded by the lava flows indicated that the youngest flows couldn't be younger than mid-Holocene and could be early Holocene or older.
Volcanic hazards
Future eruptions from Volcano Mountain would probably be lava flows, since there's a lack of
pyroclastic material. The main hazards from Volcano Mountain are
forest fires started by the lava flows. Older volcanic deposits south of Volcano Mountain indicate that lava flows may have once partly blocked or at least altered the course of the
Yukon and
Pelly Rivers. Any future activity in this area could disrupt the course of both of these major rivers and could have a serious impact on people living or working downstream.
