Yes, there is a town in Alaska that experiences an extended period of darkness each year. Utqiaġvik, formerly known as Barrow, is America's northernmost town and is renowned for its annual polar night.
Understanding the Phenomenon of Polar Night
The phenomenon experienced by Utqiaġvik is known as polar night. This occurs in regions within the Arctic and Antarctic circles during their respective winters when the sun remains below the horizon for more than 24 consecutive hours. Due to the tilt of the Earth's axis, the sun does not rise above the horizon for an extended period, leading to days (and nights) of continuous twilight or complete darkness.
Utqiaġvik's Annual Darkness
Each year, residents of Utqiaġvik prepare for a significant stretch without direct sunlight. The sun sets for the last time in mid-November and does not reappear until late January. This period plunges the town into approximately 64 days of complete darkness.
Here's a quick overview of this unique occurrence:

Life During Polar Night
While the term "complete darkness" might sound daunting, it doesn't mean absolute pitch blackness around the clock. Depending on the time of day and cloud cover, there can be periods of civil twilight, where the sky is illuminated enough to see without artificial light, albeit dimly. However, the sun itself remains entirely below the horizon.
Residents of Utqiaġvik have adapted to this unique seasonal change. The community actively embraces the polar night, engaging in various activities and ensuring access to essential services. Adjustments include:
- Reliance on Artificial Lighting: Homes, businesses, and public spaces use extensive lighting to compensate for the lack of natural light.
- Community Activities: Events and gatherings often take place indoors, fostering a strong sense of community.
- Health and Wellness: Many residents utilize light therapy lamps or maintain routines to combat seasonal affective disorder (SAD), which can be more prevalent in conditions of prolonged darkness.
- Arctic Preparedness: The town is well-equipped to handle extreme cold and continuous darkness, with robust infrastructure and community support systems.
The polar night is a fascinating natural phenomenon that profoundly shapes life in Utqiaġvik, making it a truly unique place in the world.
