The Insular Mountains are a range of mountains in the Pacific Coast Ranges on the Coast of British Columbia, Canada, comprising the Vancouver Island Ranges and Queen Charlotte Mountains. The Insular Mountains are rugged, particularly on Vancouver Island where peaks in Strathcona Provincial Park rise to elevations of more than 2,000 m (6,562 ft). The highest of these mountains is Golden Hinde on Vancouver Island, which rises to 2,196.818 m (7,207 ft).
Although the Coast Mountain Range is usually referred to as the westernmost range of the Pacific Cordillera (since it is the westernmost range on the main landmass at that point), the Insular Mountains are the true westernmost range. [1]
These Insular Mountains are not yet fully emerged above sea level, and Vancouver Island and the Haida Gwaii are just the higher elevations of the range, which was in fact fully exposed during the last glacial period (maximum ice extent about 18,000 years ago) when the continental shelf in this area was a broad coastal plain.
The Insular Mountains formed when a chain of active volcanic islands (the Insular Islands) collided against the North American continent during the mid Cretaceous period. The type of rocks that form the Insular Mountains are turbidites and pillow lavas. Granitic plutons seldom occur in the Insular Mountains, unlike the Coast Mountains. The Insular Mountain range covers some 133,879 km2 (51,691 sq mi). It experiences frequent seismic activity, with the Pacific Plate and the Juan de Fuca Plate being subducted into the Earth's mantle. Large earthquakes have led to collapsing mountains, landslides and fissures.
During the last glacial period, ice enclosed nearly all of these mountains. Glaciers that ran down to the Pacific Ocean sharpened the valley faces and eroded their bottoms. These valleys were transformed into fjords when the ice melted and the sea level rose. Ice Age remnants may still be noted, such as the Comox Glacier in the Vancouver Island Ranges.
The Elk River Mountains, located in Strathcona Provincial Park, are sometimes classified as a range. [2] [ incomplete short citation ]
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian province of British Columbia. The island is 456 km (283 mi) in length, 100 km (62 mi) in width at its widest point, and 32,100 km2 (12,400 sq mi) in total area, while 31,285 km2 (12,079 sq mi) are of land. The island is the largest by area and the most populous along the west coasts of the Americas.
Haida Gwaii, also known as the Queen Charlotte Islands, is an archipelago located between 55–125 km (34–78 mi) off the northern Pacific coast in the Canadian province of British Columbia. The islands are separated from the mainland to the east by the shallow Hecate Strait. Queen Charlotte Sound lies to the south, with Vancouver Island beyond. To the north, the disputed Dixon Entrance separates Haida Gwaii from the Alexander Archipelago in the U.S. state of Alaska.
Port Alberni is a city located on Vancouver Island in the province of British Columbia, Canada. The city lies within the Alberni Valley at the head of the Alberni Inlet, Vancouver Island's longest inlet. Port Alberni currently has a total population of 18,259.
Hecate Strait is a wide but shallow strait between Haida Gwaii and the mainland of British Columbia, Canada. It merges with Queen Charlotte Sound to the south and Dixon Entrance to the north. About 140 kilometres (87 mi) wide at its southern end, Hecate Strait narrows in the north to about 48 kilometres (30 mi). It is about 260 kilometres (160 mi) in length.

The Regional District of Comox-Strathcona was a regional district of British Columbia, Canada, from 1967 to 2008. On February 15, 2008, the regional district was abolished and replaced by two successor regional districts, Comox Valley and Strathcona.
The British Columbia Coast, popularly referred to as the BC Coast or simply the Coast, is a geographic region of the Canadian province of British Columbia. As the entire western continental coastline of Canada along the Pacific Ocean is in the province, it is synonymous with being the West Coast of Canada.
The Vancouver Island Ranges, formerly called the Vancouver Island Mountains, are a series of mountain ranges extending along the length of Vancouver Island which has an area of 31,788 km2 (12,273 sq mi). The Vancouver Island Ranges comprise the central and largest part of the island. The Geological Survey of Canada refers to Vancouver Island, Haida Gwaii, and the Alaska Panhandle as the Insular Belt including the sea floor out to 100 km (62 mi) west of Vancouver Island. The Vancouver Island Ranges are a sub-range of the Insular Mountains.
The Insular Islands were an extended chain of volcanic islands forming an arc in what is now the Pacific Ocean during the Paleozoic and Mesozoic eras. The islands formed by subduction and melting of the Farallon Plate along a fragment upon which they rose called the Insular Plate. They were bounded by the Panthalassic Ocean to the west and the Bridge River Ocean to the east. They probably formed as a composite of several volcanic chains near the equator, offshore of continental landmasses, by the Carboniferous Period around 300-325 million years ago.
The geology of the Pacific Northwest includes the composition, structure, physical properties and the processes that shape the Pacific Northwest region of North America. The region is part of the Ring of Fire: the subduction of the Pacific and Farallon Plates under the North American Plate is responsible for many of the area's scenic features as well as some of its hazards, such as volcanoes, earthquakes, and landslides.
During the Age of Discovery, the Spanish Empire undertook several expeditions to the Pacific Northwest of North America. Spanish claims to the region date to the papal bull of 1493, and the Treaty of Tordesillas signed in 1494. In 1513, this claim was reinforced by Spanish explorer Vasco Núñez de Balboa, the first European to sight the Pacific Ocean, when he claimed all lands adjoining this ocean for the Spanish Crown. Spain only started to colonize the claimed territory north of present-day Mexico in the 18th century, when it settled the northern coast of Las Californias.
Alberni Inlet is a long, narrow inlet in Vancouver Island, British Columbia, Canada, that stretches from the Pacific Ocean at Barkley Sound about 54.3 km (34 mi) inland terminating at Port Alberni. It was named by the Spanish explorer Francisco de Eliza after Pedro de Alberní y Teixidor, Captain of the Free Company of Volunteers of Catalonia who was appointed in the Spanish fort in Nootka Sound from 1790 to 1792. The inlet includes traditional territories of the Ucluelet, Uchucklesaht, Huu-ay-aht, Hupacasath, and Tseshaht peoples, who are part of the Nuu-chah-nulth Tribal Council people.
Alberni Valley is a broad valley located at the head of Alberni Inlet on Vancouver Island in British Columbia, Canada. It is home to Port Alberni, Sproat Lake and other outlining areas. The term is largely used as a synonym for Greater Port Alberni and adjoining communities but is used in a larger regional sense as well. Various local organizations and companies use the term "Alberni Valley" in their name, e.g. the Alberni Valley Times and Alberni Valley News newspapers the Alberni Valley Chamber of Commerce and the Alberni Valley Bulldogs minor hockey team. The Canadian pioneer, Joe Drinkwater lived in Alberni Valley during the late nineteenth and early twentieth centuries.
Princess Royal was a British merchant ship that sailed on fur trading ventures in the late 1780s, and was captured at Nootka Sound by Esteban José Martínez of Spain during the Nootka Crisis of 1789. Called Princesa Real while under the Spanish Navy, the vessel was one of the important issues of negotiation during the first Nootka Convention and the difficulties in carrying out the agreements. The vessel also played an important role in both British and Spanish exploration of the Pacific Northwest and the Hawaiian Islands. In 1790, while under Spanish control, Princesa Real carried out the first detailed examination of the Strait of Juan de Fuca by non-indigenous peoples, finding, among other places, the San Juan Islands, Haro Strait, Esquimalt Harbour near present-day Victoria, British Columbia, and Admiralty Inlet.
The Bonanza Range is a small mountain range on Vancouver Island, British Columbia, Canada, located in the area between the Nimpkish River and the Tsitika River. It has an area of 150 km2 and is a subrange of the Vancouver Island Ranges which in turn form part of the Insular Mountains.
The Yakoun River is the largest river of Haida Gwaii, in the province of British Columbia, Canada. Located on Graham Island it flows about 58 km (36 mi) from Yakoun Lake north to Masset Inlet, a large saltwater bay located in the heart of the Graham Island and connected to the Pacific Ocean at Dixon Entrance via a long narrow inlet called Masset Sound.
Slatechuck Mountain, known as Kaagan in the Haida language, is a summit on south-central Graham Island in Haida Gwaii, formerly known as the Queen Charlotte Islands of the North Coast of British Columbia, Canada. It is located about 9 km west of Daajing Giids, on Skidegate Inlet, and just south of Yakoun Lake, the island's largest lake, which is the source of the northward-flowing Yakoun River.
The Pelham Range is a small mountain range on southern Vancouver Island, British Columbia, Canada, located northeast of Sarita and between the Sarita River and the Alberni Inlet. It has an area of 52 km2 and is a subrange of the Vancouver Island Ranges which in turn form part of the Insular Mountains.
Kildonan is an unincorporated community in the Alberni Inlet-Barkley Sound region of the west coast of southern Vancouver Island, British Columbia. The former steamboat landing and ferry dock is on the east shore of Uchuchklesit Inlet, which branches northwest of the lower reaches of Alberni Inlet. Adjacent to Pacific Rim National Park Reserve, the locality is by road and ferry about 120 kilometres (75 mi) southwest of Port Alberni.
Union was an American sloop built in Somerset, Massachusetts in 1792. It is best known for its circumnavigation of the world, 1794–1796, under the maritime fur trader John Boit.
