Saharan Dust

Here it is, fine, fine particles collected on the edge of our veranda roof.  The particles had flown on the winds for thousands of kilometers until temperature and humidity started water droplets falling through that air, picking up the dust. Or perhaps the dust acted as the seed, giving the water vapour something to condense onto, before falling from the clouds to land on on our village.
That's an impressive journey, from a sandstorm in the Sahara, across the Mediterranean Sea, up over Europe until finally falling out of the sky onto the snow-covered landscapes of mid-Sweden....
We took a shorter journey, on snowshoes, but that's another story.
