Photographer Ed Gold went deep into the Alaskan wilderness to meet the Atchley family, who have lived there in near-isolation for 18 years. The family of four buys groceries once a year, and live off the land by hunting black bears, wolves, rabbits, ducks and beavers.

The family keep their own time to suit their needs, putting the clock as much as three hours forward or back depending on the light.

They generally eat breakfast at 16:30, spending the short winter daylight hours busy with carpentry, cleaning and repairs. After supper at about 22:00, they fill the rest of their day with talking, guitar playing and writing, going to bed around 04:00.

If they feel short of money, 52-year-old David will sell tanned hides, build log cabins or take work in the local gold mine, about 100 miles away.

However, by living off the land and using solar power, they manage to survive on just $12,000 (£9,600) a year.
