60th parallel north
Although it lies approximately twice as far away from the Equator as from the North Pole, the 60th parallel is half as long as the Equator line. This is where the Earth bulges halfway as much as on the Equator.
At this latitude, the Sun is visible for 18 hours, 52 minutes during the June solstice and 5 hours, 52 minutes during the December solstice. The maximum altitude of the Sun is 53.44° on 21 June and 6.56° on 21 December. The maximum altitude of the Sun is > 15.00º in October and > 8.00º in November.
The lowest latitude where white nights can be observed is approximately on this parallel.
Around the world
Starting at the Prime Meridian and heading eastwards, the parallel 60° north passes through:
In Canada, the 60th parallel constitutes the mainland boundary between the northern territories of Yukon, Northwest Territories, and Nunavut to the north, and the western provinces of British Columbia, Alberta, Saskatchewan, and Manitoba to the south.
Accordingly, "north of 60" is an expression often used for the territories, although parts of Nunavut (the islands in Hudson Bay and James Bay) are located south of the 60th parallel, and parts of Quebec and Newfoundland and Labrador are located north, to the east of Hudson Bay. A 1990s TV show on CBC about life in the Northwest Territories was called North of 60.
Canada's only four corners are located at the intersection of the 60th parallel and the 102nd meridian west, between the Northwest Territories, Nunavut, Saskatchewan, and Manitoba. However, this is not a true quadripoint as the measurement of the Saskatchewan/Manitoba border in the 1880s placed it approximately 400 metres (440 yd) west of the 102nd meridian, which defines part of the Northwest Territories/Nunavut border.
Between 1776 (leap year starting on Monday) and 1950 (common year starting on Sunday), the 60th parallel formed the southern limit of the Royal Greenland Trade Department's exclusive monopoly on trade near the Dano-Norwegian and later Danish colonies of Greenland (1776–1782) and South Greenland (1782–1950).
