interior dimensions

The Interior Mountains or Northern Interior Mountains are the semi-official names for an expansive collection of mountain ranges that comprises much of the northern half 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.
