Boundary Ranges Subrange of the Coast Mountains in Alaska, British Columbia, and Yukon

The Boundary Ranges, also known in the singular and as the Alaska Boundary Range, are the largest and most northerly subrange of the Coast Mountains. They begin at the Nass River, near the southern end of the Alaska Panhandle in the Canadian province of British Columbia and run to the Kelsall River, near the Chilkoot Pass, beyond which are the Alsek Ranges of the Saint Elias Mountains, and northwards into the Yukon Territory flanking the west side of the Yukon River drainage as far as Champagne Pass, north of which being the Yukon Ranges. To their east are the Skeena Mountains and Stikine Plateau of the Interior Mountains complex that lies northwest of the Interior Plateau; the immediately adjoining subregion of the Stikine Plateau is the Tahltan Highland. To their northeast is the Tagish Highland, which is a subregion of the Yukon Plateau. Both highlands are considered in some descriptions as included in the Coast Mountains. The Alexander Archipelago lies offshore and is entirely within Alaska.

Tuya volcanic field mountain in Canada

The Tuya volcanic field is a volcanic field of tuyas located in far northern British Columbia, Canada, near the border with the Yukon Territory and focused on the area of the Tuya Range, a subrange of the Stikine Ranges of the Cassiar Mountains, though some vents are in the Kawdy Plateau, the northernmost part of the Stikine Plateau. Several small shield volcanoes, and postglacial lapilli cones and lava flows have been reported in this area. The only nonglacial volcanoes in the field are Gabrielse Cone and the West Tuya lava field.

Stikine Icecap glacier in Canada

The Stikine Icecap is a large icefield straddled on the Alaska–British Columbia boundary in the Alaska Panhandle region. It lies in the Boundary Ranges of the Coast Mountains. Within the United States, most of it is under the administration of the Tongass National Forest and is part of the Stikine-LeConte Wilderness within the national forest.

Cassiar Mountains Mountain range in British Columbia and Yukon, Canada

The Cassiar Mountains are the most northerly group of the Northern Interior Mountains in the Canadian province of British Columbia and also extend slightly into the southernmost 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. They form a section of the Continental Divide, that, in this region, separates water drainage between the Arctic and Pacific Oceans. Physiographically, they are a section of the larger Yukon-Tanana Uplands province, which in turn are part of the larger Intermontane Plateaus physiographic division.

The Stikine Ranges are a group of mountain ranges and mountainous plateaus in northwestern British Columbia, Canada. They are the northernmost subdivision of the Cassiar Mountains and among the least explored and most undeveloped parts of the province.

Toozaza Peak is a tuya in the Stikine Ranges of the Cassiar Mountains in northern British Columbia, Canada, located in the Iverson Creek. Toozaza Peak is the summit of a north-south aligned ridge between the head of Toozaza Creek and the head of the Jennings River, just south of the Jennings' divide with the Little Rancheria River headwaters. The Little Rancheria and Toozaza Creek are part of the Liard, while the Jennings is part of the Yukon River drainage via Teslin Lake, and the peak therefore stands astride the line of the Continental Divide. It is part of the Tuya Volcanic Field, a volcanic field associated with the Stikine Volcanic Belt, part of the Northern Cordilleran Volcanic Province.

Stikine Country

The Stikine Country, also referred to as the Stikine District or simply "the Stikine", is one of the historical geographic regions of the Canadian province of British Columbia, located inland from the central Alaska Panhandle and comprising the basin of the Stikine River and its tributaries. The term Stikine–Iskut is also fairly common to describe the area, and references the Iskut River, the Stikine's largest tributary and describable as its south fork.

The Metsantan Range are a mountain range between the upper Stikine and the Finlay River drainages in northern British Columbia, Canada. It has an area of 1116 km2 and is a subrange of the Omineca Mountains which in turn form part of the Interior Mountains.

The Stikine Plateau is a plateau in northern British Columbia, Canada. It lies between the Boundary Ranges of the Coast Mountains on the west and southwest and the Cassiar Mountains along its northeast, and between the Skeena Mountains on its south and southeast and the Jennings and Nakina Rivers on the north.

The Boundary Range, formerly known as the Boundary Mountains, is a subrange of the similarly named but much larger Boundary Ranges which run most of the length of the border between British Columbia, Canada, and Alaska, United States. The range lies west of the lower Stikine River between the Mud (S) and Flood Glaciers (N).

The Spatsizi Plateau is a plateau in the upper basin of the Stikine River in north-central British Columbia, Canada. Most of the plateau, which is a sub-plateau of the Stikine Plateau, is enshrined in either Spatsizi Plateau Wilderness Provincial Park or Spatsizi Headwaters Provincial Park. It is flanked on the south and southwest by the Skeena Mountains, on the southeast by the Omineca Mountains, on the northeast by the Stikine Ranges of the Cassiar Mountains, and on the west by the Klastline Plateau.

The Tanzilla Plateau is a plateau in the Stikine Country of the Northern Interior of British Columbia, Canada. It is a sub-plateau of the Stikine Plateau and is located east of the Tuya River, north of the Stikine River and surrounding Dease Lake; its eastern extremity verges on the Stikine Ranges of the Cassiar Mountains at Dark Mountain and Pyramid Mountain. The Spatsizi Plateau is to the southeast, the Klastline Plateau to the south, the Tahltan Highland to the west and southwest, and the Kawdy Plateau to the west and northwest. All are also sub-plateaus of the Stikine Plateau.
