The Volcano, also known as
Lava Fork volcano, is the name of a cinder cone in northwestern British
Columbia
, Canada
, located
immediately north of the British Columbia-Alaska
border.
Geology
The Volcano is probably the youngest volcano in Canada.
Lava flows traveled south 5 km where they crossed
the border into Alaska
and dammed
the Blue River, a short tributary of the Unuk River
flowing from the southeast flank of Mount Lewis Cass (Boundary Peak 47).
In doing so it formed several small
lakes. The
lava flows are approximately 22 km long, and still have the
original features and pits formed when the overlying solidified
lava collapsed into underlying
lava tubes
and
tree mold.
The youngest of these lava flows could be only 150 years old and
the oldest eruption is possibly 350 years old. Volcanic activity at
The Volcano was reported in 1904, however this eruption is
considered uncertain.
The Volcano is the southernmost of ten
volcanoes in the Iskut volcanic field, which includes volcanoes at
Hoodoo
Mountain
and the
Iskut-Unuk River
Cones
.
The
Volcano is one of the top 10 Canadian volcanic areas with recent
seismic activity, the others include:
Castle
Rock
, Mount Edziza volcanic complex
, Mount
Cayley
, Hoodoo
Mountain
, Crow Lagoon
, Silverthrone Caldera
, Mount
Meager
, Wells Gray-Clearwater volcanic
field
and Mount Garibaldi
.
Volcanic hazards
Because The Volcano is located in the remote Iskut region and
involves passive lava flows, future eruptions at The Volcano pose
little threat. Damming of rivers and other local water courses may
disrupt fish habitat.
Clouds of volcanic
ash could threaten lower-flying aircraft along the northern coastal corridor
between Vancouver
and Alaska
. Lava
Fork is not being seismically monitored to warn of any future
activity.
