British Columbia in the context of "Contiguous United States"

Alaska (/əˈlæskə/ ə-LASS-kə) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Asian Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. It is a semi-exclave of the U.S., and is the largest exclave in the world.

Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division in the world. It is the U.S. state with third-least populous, most sparsely populated, and closest to another continent which is Asia. With a population of 740,133 in 2024, it is the most populous territory in North America located mostly north of the 60th parallel, with more than quadruple the combined populations of Northern Canada and Greenland. Alaska contains the four largest cities in the United States by area, including the state capital of Juneau. Alaska's most populous city is Anchorage, and approximately half of Alaska's residents live within its metropolitan area.

A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.

Vancouver is a major city in Western Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2021 Canadian census recorded 662,248 people in the city, up from 631,486 in 2016. The Metro Vancouver area had a population of 2.6 million in 2021, making it the third-largest metropolitan area in Canada. Greater Vancouver, along with the Fraser Valley, comprises the Lower Mainland with a regional population of over 3 million. Vancouver has the highest population density in Canada, with over 5,700 inhabitants per square kilometre (15,000/sq mi), and the fourth highest in North America (after New York City, San Francisco, and Mexico City).

Vancouver is one of the most ethnically and linguistically diverse cities in Canada: 49.3 percent of its residents are not native English speakers, 47.8 percent are native speakers of neither English nor French, and 54.5 percent of residents belong to visible minority groups. It has been consistently ranked one of the most liveable cities in Canada and in the world. In terms of housing affordability, Vancouver is also one of the most expensive cities in Canada and in the world. Vancouverism is the city's urban planning design philosophy.

The Numbered Treaties (or Post-Confederation Treaties) are a series of eleven treaties signed between the First Nations, one of three groups of Indigenous Peoples in Canada, and the reigning monarch of Canada (Victoria, Edward VII or George V) from 1871 to 1921. These agreements were created to allow the Government of Canada to pursue settlement and resource extraction in the affected regions, which includes the entirety of modern-day Alberta, Manitoba, and Saskatchewan, as well as parts of modern-day British Columbia, Ontario, the Northwest Territories, Nunavut, and Yukon. These treaties expanded the Dominion of Canada resulting in the displacement of Indigenous populations for large tracts of land in exchange for promises made to the indigenous people of the area. These terms were dependent on individual negotiations and so specific terms differed with each treaty.

These treaties came in two waves—Numbers 1 through 7 from 1871 to 1877 and Numbers 8 through 11 from 1899 to 1921. In the first wave, the treaties were key in advancing European settlement across the Prairie regions as well as the development of the Canadian Pacific Railway. In the second wave, resource extraction was the main motive for government officials. During this time, Canada introduced the Indian Act extending its control over the First Nations to education, government and legal rights. The federal government did provide emergency relief, on condition of the Indigenous peoples moving to the Indian reserve.

Yukon (Canadian French: [jukõ]) is a territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada's westernmost and smallest territory by land area. As of the 2021 census, Yukon is the middle of the three territories in terms of population, but the most densely populated. As of the 2025 third quarter estimates Yukon had a population of 48,278, which would make it the most populated territory. Whitehorse, the territorial capital, is the largest settlement.

Yukon was split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is the Yukon Act passed by the federal Parliament in 2002. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbreviation of YT. In 2021, territorial government policy was changed so that The Yukon is recommended for use in official territorial government materials.

Montana (/mɒnˈtænə/ mon-TAN-ə) is a landlocked state in the Mountain West subregion of the Western United States. It is bordered by Idaho to the west, North Dakota to the east, South Dakota to the southeast, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, but the eighth-least populous state and the third-least densely populated state. Its capital is Helena, while the most populous city is Billings. The western half of the state contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state.

Most of Montana first came under American sovereignty with the Louisiana Purchase from France in 1803 and was explored by the Lewis and Clark Expedition shortly thereafter. Fur trappers followed and were the main economic activity in the area until gold was discovered in 1852. The ensuing gold rush, along with the passage of the Homestead Acts in 1862, brought large numbers of American settlers to Montana. Rapid population growth and development culminated in statehood on November 8, 1889. Mining, particularly around Butte and Helena, would remain the state's main economic engine through the mid-20th century.
