Located deep in Siberia, the village of Oymyakon holds the title of the coldest permanently inhabited place on Earth, tied with Verkhoyansk.

From December to February, the weather in the tiny village (population 500) plummets to -50°F (-45C), with a record low of -90°F (-68C) registered in 1933. At those temperatures, a naked human left outside would freeze to death in under a minute.

The extreme conditions are partly due to the fact that the hamlet lies between two large ranges that trap arctic air between them; it is actually significantly warmer on the mountains than in the valley below.

Surprisingly, summers in Oymyakon can be very mild, even hot; the town is also a growing tourist destination.
