...this image was taken during a trip through the USA. It was a sunny, hot and cloudless day, I spent in the Great Sand Dunes National Park, Colorado.
But I hoped, that some clouds would appear over the the dunes.
At the evening I saw a few clouds, so I decided to walk into the sand dunes.
After 1 hour walking to a higher dune, the weather changed, a strong wind blew and a huge weather front was over the desert.

I took many shots, but suddenly I noticed these two people, walking up to another dune.
It was a perfekt moment: These two hikers, the great cloudscape and the evening light.
