Located above the Arctic Circle, Utqiagvik is the northernmost settlement in the United States. Formerly known as Barrow, the town of nearly 5,000 people is mostly populated by indigenous Iñupiat, but also with a growing immigrant population.  Roads in the community are left mostly unpaved, due to the permafrost.   (John Moore)

Due to the tilt of the Earth's axis, the Sun will not rise above the horizon in Utqiagvik for the next 64 days. But the Alaskan borough will not be in complete darkness and will experience a few hours of what's known as civil twilight, which is the pale blue light normally seen before dawn.

Utqiagvik is about 500 miles northwest of Fairbanks, and is home to roughly 4,400 people, with archeological sites dating back to 500 CE, according to the city's website.

Without the light of the Sun and daytime heating, temperatures plummet during Polar Night across the Arctic Circle.

ACTIVE END TO NOVEMBER COULD LEAD TO POTENTIAL POLAR VORTEX INFUSED COLD AND SNOW TO START DECEMBER

The Polar Night phenomenon also plays a role in the formation of the Polar Vortex, the area of extremely cold air in the Earth's stratosphere.

Without sunlight, this region above the layer of atmosphere where weather occurs, the troposphere, becomes extremely cold. Although occasionally, this arctic air seeps below the stratosphere and is able to move south over the Lower 48.

WHAT IS THE POLAR VORTEX

While winters in Utqiagvik feature more than 60 days of darkness, in the summer, the city experiences nearly three months of total sunlight.

In the warmer months, Utqiagvik is also home to America's northernmost football team, during football season at Barrow High School
