There are four main groupings, the [Skeena](/source/Skeena_Mountains), [Cassiar](/source/Cassiar_Mountains) and [Omineca Mountains](/source/Omineca_Mountains) to the north of the [Interior Plateau](/source/Interior_Plateau) between the [Coast Mountains](/source/Coast_Mountains) to the west and the [Rocky Mountains](/source/Rocky_Mountains) to the east, and the [Hazelton Mountains](/source/Hazelton_Mountains) along the Interior Plateau's northwestern flank against the Coast Mountains, extending from the [Bulkley Ranges](/source/Bulkley_Ranges) south to the [Bella Coola River](/source/Bella_Coola_River). Included within the Interior Mountains system is the [Stikine Plateau](/source/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](/source/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. ## Etymology The terms *Interior Mountains* and *Northern Interior Mountains* were coined by British Columbia government geographer Stuart Holland in the course of writing his *Landforms of British Columbia*, which is a definitive volume on the province's topography and [toponymy](/source/Toponymy) written in 1964. This work is used as the basis for official toponymies such as those in the provincial gazette and the [British Columbia Geographic Names Information System Database](/source/British_Columbia_Geographic_Names_Information_System_Database) (BCGNIS), which is the official registry of the province's geographic names. The term Interior Mountains, used by Holland throughout his work and as a chapter heading describing the mountain system in question, is not present in the Geographical Names Database despite being a chapter heading and appearing on Holland's map of the province's landform systems. He suggests, also, the term "Northern Interior Mountains", partly because the mountain system is in a region also known as the [Northern Interior](/source/British_Columbia_Interior), but also to potentially distinguish this mountain system from mountain ranges farther south in the province's Interior, including those of the [Interior Plateau](/source/Interior_Plateau). In his exegesis, he decided on "Interior Mountains" for reasons of brevity. ## Component ranges and plateaus Major mountain ranges and plateaus that are considered part of the Interior Mountains are included. ### [Cassiar Mountains](/source/Cassiar_Mountains) - [Dease Plateau](/source/Dease_Plateau) - [Kechika Ranges](/source/Kechika_Ranges) - [Sifton Ranges](/source/Sifton_Ranges) - [Stikine Ranges](/source/Stikine_Ranges) ### [Hazelton Mountains](/source/Hazelton_Mountains) - [Bulkley Ranges](/source/Bulkley_Ranges) - [Kispiox Range](/source/Kispiox_Range) - [Nass Ranges](/source/Nass_Ranges) - [Pattullo Range](/source/Pattullo_Range) - [Tahtsa Ranges](/source/Tahtsa_Ranges) ### [Omineca Mountains](/source/Omineca_Mountains) - [Finlay Ranges](/source/Finlay_Ranges) - [Hogem Ranges](/source/Hogem_Ranges) - [Metsantan Range](/source/Metsantan_Range) - [Samuel Black Range](/source/Samuel_Black_Range) - [Swannell Ranges](/source/Swannell_Ranges) - [Tatlatui Range](/source/Tatlatui_Range) ### [Skeena Mountains](/source/Skeena_Mountains) - [Atna Range](/source/Atna_Range) - [Babine Range](/source/Babine_Range) - [Bait Range](/source/Bait_Range) - [Driftwood Range](/source/Driftwood_Range) - [Klappan Range](/source/Klappan_Range) - [Oweegee Range](/source/Oweegee_Range) - [Sicintine Range](/source/Sicintine_Range) - [Slamgeesh Range](/source/Slamgeesh_Range) - [Strata Range](/source/Strata_Range) - [Takla Range](/source/Takla_Range) ### [Stikine Plateau](/source/Stikine_Plateau) - [Kawdy Plateau](/source/Kawdy_Plateau) - [Nahlin Plateau](/source/Nahlin_Plateau) - [Spatsizi Plateau](/source/Spatsizi_Plateau) - [Tagish Highland](/source/Tagish_Highland) (NB sometimes defined as part of the [Coast Mountains](/source/Coast_Mountains)) - [Tahltan Highland](/source/Tahltan_Highland) (NB sometimes defined as part of the [Coast Mountains](/source/Coast_Mountains)) - [Taku Plateau](/source/Taku_Plateau) (NB sometimes defined as part of the [Yukon Plateau](/source/Yukon_Plateau)) - [Tanzilla Plateau](/source/Tanzilla_Plateau) ## Parks and protected areas - [Boya Lake Provincial Park](/source/Boya_Lake_Provincial_Park) - [Dall River Old Growth Provincial Park](/source/Dall_River_Old_Growth_Provincial_Park) - [Denetiah Provincial Park](/source/Denetiah_Provincial_Park) - [Dune Za Keyih Provincial Park and Protected Area](/source/Dune_Za_Keyih_Provincial_Park_and_Protected_Area) - [Horneline Creek Provincial Park](/source/Horneline_Creek_Provincial_Park) - [Hyland River Provincial Park](/source/Hyland_River_Provincial_Park) - [Kinaskan Lake Provincial Park](/source/Kinaskan_Lake_Provincial_Park) - [Mount Edziza Provincial Park](/source/Mount_Edziza_Provincial_Park) - [Rainbow Alley Provincial Park](/source/Rainbow_Alley_Provincial_Park) - [Spatsizi Plateau Wilderness Provincial Park](/source/Spatsizi_Plateau_Wilderness_Provincial_Park) - [Stikine River Provincial Park](/source/Stikine_River_Provincial_Park) - [Todagin South Slope Provincial Park](/source/Todagin_South_Slope_Provincial_Park) - [Tuya Mountains Provincial Park](/source/Tuya_Mountains_Provincial_Park) ### Proposed protected areas - [Sacred Headwaters](/source/Sacred_Headwaters) ## See also - [Interior Plateau](/source/Interior_Plateau) ## References - S.
