From Wikipedia, the free encyclopedia
The Cassiar Mountains are the most northerly group of the Northern Interior Mountains in the Canadian province of British Columbia and the Yukon Territory. They lie north and west of the Omineca Mountains, west of the northernmost Rockies and the Rocky Mountain Trench, north of the Hazelton Mountains and east of the Boundary Ranges. Physiographically, they are a section of the larger Yukon-Tanana Uplands province, which in turn are part of the larger Intermontane Plateaus physiographic division.
In the western Cassiar Mountains lie the remnants of a prehistoric shield volcano called the Maitland Volcano which formed between 5 and 4 million years ago during the Pliocene period.
The highest mountain in the Cassiar Mountains is Thudaka Peak at 2,748 m (9,016 ft).[1]
