It is late September and in the Advent Valley outside Longyearbyen autumn and winter meets. The tundra is deep red, the mountains have a new layer of powder on top. The seasons at Svalbard live their own lives. It's winter, followed by another winter, a moment of summer and then autumn. That is how the days, weeks and months at 78 degrees north are dancing away and if you like this dance, it is difficult to stop. Hard to leave the Arctic.
