- This article is about a certain group of mountain ranges in the Northern Interior of British Columbia and southern Yukon, as defined by a government-commissioned geographic study which forms the basis for the provincial gazette. For other mountain ranges of the British Columbia Interior and southern Yukon see Rocky Mountains, Columbia Mountains, Cascade Mountains and the subranges listed on the Interior Plateau article. For the region of British Columbia known as "The Interior", see British Columbia Interior.
The
Interior Mountains, also called the
Northern Interior Mountains and
Interior Ranges, are the semi-official names for a huge area that comprises much of the northern two thirds of the
Canadian province of
British Columbia and a large area of southern
Yukon. There are four main groupings, the
Skeena,
Cassiar and
Omineca Mountains to the north of the
Interior Plateau between the
Coast Mountains to the west and the
Rocky Mountains to the east, and the
Hazelton Mountains along the Interior Plateau's northwestern flank against the Coast Mountains, extending from the
Bulkley Ranges south to the
Bella Coola River. Included within the Interior Mountains system is the
Stikine Plateau, which contains a number of sub-plateaus and various mountain ranges and is located west of the Cassiars, north of the Skeenas, and to the east of the
Boundary Ranges of the Coast Mountains. Most of the thousands of summits in the Interior Mountains are unnamed, and they are mostly uninhabited and undeveloped.
