This month, the sun will set on Barrow, Alaska and remain below the horizon for 65 days.
Barrow has a population of about 4,000 and is the northernmost town in the United States. The average high temperature remains below zero from December through March in Barrow.
The town is extremely isolated, surrounded by wilderness tundra and not accessible by road.
Many people in Barrow, including the significant population of Alaska Natives, rely on the Arctic Ocean for subsistence.
But Barrow is also home to several research facilities that bring in jobs, and oil and gas tax revenues allow the town to enjoy modern conveniences such as running water, sewers, and a health clinic.
People who live there say they enjoy the community and culture that’s unique to their town.
Documentary series One Square Mile visited Barrow in 2012 to give outsiders an idea of what life is like in a polar climate 320 miles north of the Arctic Circle.
The sun sets in November and doesn't rise again until January. And in mid-May, the sun rises and does not set again for about 80 days.
The high winds and cold temperatures get dangerous in the winter -- if you go outside without gloves on, fingers can get frostbitten within minutes.
There are thousands more caribou than people in the land surrounding Barrow, according to one resident.
There are four grocery stores in town, and prices are ridiculously high because all of the food has to be flown in.
Some food doesn't make it through the extreme weather. This entire palette of soda had to be thrown out when it froze. It was delivered in -50 degree temperatures.
The grocer doesn't like his job, but he says he can't think about retirement. 'I used to drive out in the tundra, look back at Barrow, and ask myself, 'What am I doing here?' ... It's not about money anymore. It's about responsibility.'
More than half of Barrow workers are government employees, and the median household income is about $US89,000, allowing families to afford the cost of living.
He met his wife while driving his cab (thankfully, cabs rides in Barrow are cheaper than they are in the rest of the country).
His wife says it was a relief to marry someone who didn't grow up in Barrow, noting, 'When I met my husband, I didn't have to come home and ask my grandmother if I'm related to him.'
She says many pop culture icons -- such as Hannah Montana and Justin Bieber -- are popular with kids in Barrow.
Fran Tate runs a popular Mexican restaurant called Pepe's North of the Border. She opened it in 1978.
Tate moved to Barrow to work for the Naval Arctic Research Lab and stayed because she liked the culture. 'In the lower 48, they're always trying to live up to something, and you don't have to do that here. People take you for what you are.'
Church is also big in Barrow when the weather is good. Not many people show up when the temperature drops to -35 degrees, but attendance is high when it's above -20 degrees.
Life in such a dark and isolated place can cause problems. Police say that suicide, depression, and substance abuse is common.
This cop says that 'it can be extremely difficult to live here if you're not from here.' He's from Oregon and says he misses trees, mountains, and hills.
Because of the constant darkness in the winter, it can be hard to tell the days apart. Some people call the police station to ask what day or time it is.
And it is a tight-knit community -- this teacher says she's related in some way to 80-90% of her students.
Despite its challenges, locals say Barrow is a good place to raise a family. The teacher told the documentary crew: 'I'm glad my kids have graduated from here and have been raised in this community. It's part of their heritage.'
