Interior Plateau - Mountain Ranges

Mountain Ranges

Several mountain ranges and hill-systems are included in the definition of this region. Among these are:

• the Pavilion Range includes:
  • The Clear Range (includes the Scarped Range)
  • The Marble Range
  • The Cornwall Hills (not formally part of the Pavilion Range, but adjoining the Clear Range on its east)
  • The Trachyte Hills (not formally part of the Pavilion Range, but adjoining the Clear and Marble Ranges on their east)
• The Arrowstone Hills (SW edge of the Bonaparte Plateau)
• The Rainbow Range (sometimes assigned to either the Pacific Ranges or Kitimat Ranges subranges of the Coast Mountains)
• The Itcha Range
• The Ilgachuz Range
• The Quanchus Range (western edge of the Nechako Plateau, in the midst of the Nechako Reservoir/Ootsa Lake)
• The Telegraph Range (Nechako Plateau)
• The Fawnie Range (Nechako Plateau)
• The Pattullo Range (sometimes classified as part of the Hazelton Mountains)

Some classifications systems assign the Pattullo Range to the Hazelton Mountains, which are part of the larger Skeena Mountains complex, but then theoretically also is the Quanchus Range. Also, the Cariboo Mountains are sometimes included as part of the Interior Plateau.

Three areas liminal to the plateau, i.e. sometimes considered part of it rather than the adjoining mountain ranges, are the Shuswap Highland, Okanagan Highland and Quesnel Highland.
