Area: 49668 sq km.
Location: The Stikine Ranges are the main spine and largest group of the Cassiar Mountains, and extend from the head of the Chukachida River and the lower Finlay River on the SE end into the Yukon Territory. Their eastern boundary is a series of valleys running via the Rapid, Dall and Frog Rivers, which is also the western limit of the Kechika Ranges (south of the Major Hart; north of that the area in between the two groups of ranges is undefined, i.e. NE of the Rapid River). Their western boundary is with the Stikine Plateau, but this is indeterminate in Holland and has here been drawn in a somewhat arbitrary line from Chukachida Lake to Dease Lake via the Tanzilla River; some of the mountains east of this line may be meant to be part of the Stikine Plateau but Holland specifies King Mountain, in the Three Sisters Range SE of Dease Lake, as being part of the Stikine Ranges, which is just inside the boundary charted here.
