The Interior Mountains are a huge group of mountain ranges. They cover a big part of northern British Columbia and southern Yukon in Canada. You might also hear them called the Northern Interior Mountains.

These mountains are mostly wild and untouched. Most of their thousands of peaks don't even have names! They are not very populated or developed.

There are four main groups of mountains here:

The Stikine Plateau is also part of the Interior Mountains system. It has many smaller plateaus and mountain ranges. This plateau is west of the Cassiars, north of the Skeenas, and east of the Boundary Ranges (which are part of the Coast Mountains).

How the Mountains Got Their Name

Naming the Interior Mountains

The names Interior Mountains and Northern Interior Mountains were first used by a British Columbia government geographer named Stuart Holland. He wrote a very important book in 1964 called Landforms of British Columbia. This book describes the shapes of the land and the names of places in the province.

Holland used the term "Interior Mountains" throughout his book. He even used it as a chapter title for this mountain system. This name is now used as a basis for official names, like those in the provincial records.

Why "Interior Mountains"?

Stuart Holland also suggested "Northern Interior Mountains." He thought this name might help tell these mountains apart from other ranges further south in British Columbia's Interior. However, he decided to use "Interior Mountains" because it was shorter and easier to say.
