The
Ilgachuz Range is a name given to an
extinct shield volcano in
British Columbia,
Canada. It is not a mountain range in the normal sense, because it was formed as a single volcano that has been
eroded for the past 5 million years. It lies on the
Chilcotin Plateau, located some north-northwest of
Vancouver and 30 km north of
Anahim Lake. The highest peak of the range is
Far Mountain. The range supports a unique
grassland ecosystem. This type of grassland has not been seen anywhere else in central and southern British Columbia. The climate is cool and dry; typical of higher elevations of the
Interior Plateau.
