High above the cloud / fog. Las Agujas de El Cancho Gordo. Madrid under a thick blanket of fog.

Granite and fog.
La Sierra de La Cabrera. Climbing through the fog, not knowing if the peaks would poke out from under, was interesting. Much better was when I eventually did break through!
Later that day I watched the weather news and it seems that the sea of fog stretched over the whole of the central Iberian Peninsula; an unusual phenomenum!.
