Snag is a village located on a small, dry-weather sideroad off the Alaska Highway, 25 kilometres (16 mi) east of Beaver Creek, Yukon, Canada. The village of Snag is located in a bowl-shaped valley of the White River and its tributaries, including Snag Creek. It was first settled during the Klondike Gold Rush. An aboriginal village was also located approximately 8 kilometres (5 mi) away. It was the site of a military airfield, established as part of the Northwest Staging Route, which closed in 1968. In 1947, the village of Snag boasted a population of eight to ten First Nation people and fur traders. An additional staff of fifteen to twenty airport personnel — meteorologists, radio operators, aircraft maintenance men — lived at the airport barracks.
Snag has a subarctic climate (Köppen climate classification Dwc/Dfc) with mild summers and severely cold and long winters.
On February 3, 1947, the record-low temperature for continental North America was recorded in Snag: −63.0 °C (−81.4 °F).  That same winter, two previous records had already been surpassed: one in December noted various phenomena, particularly sound such as voices being heard clearly miles from their source. There was a clear sky (except for some ice fog), and little to no wind. There were 38.1 centimetres (15.0 in) of snow on the ground, but it was decreasing. Another town 180 km (112 mi) northeast of Snag, Fort Selkirk, claimed an even lower temperature of −65.0 °C (−85.0 °F), but the claim could not be confirmed.

Whitehorse is the capital of Yukon, and the largest city in Northern Canada. It was incorporated in 1950 and is located at kilometre 1426 on the Alaska Highway in southern Yukon. Whitehorse's downtown and Riverdale areas occupy both shores of the Yukon River, which rises in British Columbia and meets the Bering Sea in Alaska. The city was named after the White Horse Rapids for their resemblance to the mane of a white horse, near Miles Canyon, before the river was dammed.
Yukon is the smallest and westernmost of Canada's three territories. It also is the second-least populated province or territory in Canada, with a population of 43,964 as of March 2022. Whitehorse, the territorial capital, is the largest settlement in any of the three territories.

The Douglas C-54 Skymaster is a four-engined transport aircraft used by the United States Army Air Forces in World War II and the Korean War. Like the Douglas C-47 Skytrain derived from the DC-3, the C-54 Skymaster was derived from a civilian airliner, the Douglas DC-4. Besides transport of cargo, the C-54 also carried presidents, prime ministers, and military staff. Dozens of variants of the C-54 were employed in a wide variety of non-combat roles such as air-sea rescue, scientific and military research, and missile tracking and recovery. During the Berlin Airlift it hauled coal and food supplies to West Berlin. After the Korean War it continued to be used for military and civilian uses by more than 30 countries. It was one of the first aircraft to carry the President of the United States, the first being President Franklin D. Roosevelt during World War II.
Alert, in the Qikiqtaaluk Region of Nunavut, Canada, is the northernmost continuously inhabited place in the world, on Ellesmere Island at latitude 82°30'05" north, 817 kilometres (508 mi) from the North Pole. As of the 2016 census, the population was 0. All Alert residents are temporary, typically serving six-month tours of duty there. It takes its name from HMS Alert, which wintered 10 km (6.2 mi) east of the present station, off what is now Cape Sheridan, in 1875–1876.

Yukon is in the northwestern corner of Canada and is bordered by Alaska and the Northwest Territories. The sparsely populated territory abounds with natural scenic beauty, with snowmelt lakes and perennial white-capped mountains, including many of Canada's highest mountains. The territory's climate is Arctic in territory north of Old Crow, subarctic in the region, between Whitehorse and Old Crow, and humid continental climate south of Whitehorse and in areas close to the British Columbia border. Most of the territory is boreal forest with tundra being the main vegetation zone only in the extreme north and at high elevations.
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory separate Alaska from Washington state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent.
The climate of Alaska is determined by average temperatures and precipitation received statewide over many years. The extratropical storm track runs along the Aleutian Island chain, across the Alaska Peninsula, and along the coastal area of the Gulf of Alaska which exposes these parts of the state to a large majority of the storms crossing the North Pacific. The climate in Juneau and the southeast panhandle is a mid-latitude oceanic climate, in the southern sections and a subarctic oceanic climate in the northern parts. The climate in Southcentral Alaska is a subarctic climate due to its short, cool summers. The climate of the interior of Alaska is best described as extreme and is the best example of a true subarctic climate, as the highest and lowest recorded temperatures in Alaska have both occurred in the interior. The climate in the extreme north of Alaska is an Arctic climate with long, cold winters, and cool summers where snow is possible year-round.
Temperature in Canada varies widely from region to region. Winters can be harsh in many parts of the country, particularly in the interior and Prairie provinces, which experience a continental climate, where daily average temperatures are near −15 °C (5 °F), but can drop below −40 °C (−40 °F) with severe wind chills. In non-coastal regions, snow can cover the ground for almost six months of the year, while in parts of the north snow can persist year-round. Coastal British Columbia has a temperate climate, with a mild and rainy winter. On the east and west coasts, average high temperatures are generally in the low 20s °C, while between the coasts, the average summer high temperature ranges from 25 to 30 °C, with temperatures in some interior locations occasionally exceeding 40 °C (104 °F).
Waterton Park, commonly referred to as Waterton, is a hamlet in southwestern Alberta, Canada within Improvement District No. 4 Waterton.
On 26 January 1950, the Douglas C-54 Skymaster serial number 42-72469 disappeared en route from Alaska to Montana, with 44 people aboard. The aircraft made its last radio contact two hours into its eight-hour flight. Despite one of the largest rescue efforts carried out by a joint effort between Canadian and US military forces, no trace of the aircraft has ever been found. It is considered one of the largest groups of American military personnel to ever go missing.
Mount Archibald is a prominent 2,588-metre (8,491-foot) mountain summit located in the Kluane Ranges of the Saint Elias Mountains in Yukon, Canada. The mountain is situated 21 km (13 mi) west of Haines Junction, 5.9 km (4 mi) south of Mount Decoeli, and 27 km (17 mi) east-southeast of Mount Cairnes, which is the nearest higher peak. Set on the boundary line of Kluane National Park, Archibald can be seen from the Alaska Highway, weather permitting. The mountain was named after Edgar Archibald (1885-1968), a Canadian agricultural scientist. The mountain's name was officially adopted August 12, 1980, by the Geographical Names Board of Canada. On a clear day, the summit offers views deep into Kluane National Park of giants such as Mt. Logan, Mt. Vancouver, and Mt. Kennedy.
