Hi Anne, Islas Graciosa, is a very small island just north of Lanzarote, the northernmost and most desolate of the Canary Islands. There is a small ferry that runs to Graciosa. There are no paved roads and only one village. Along the shore you can find these strange cylinders. They are the size of the end of my thumb and look like they are made of dust colored clay. Many have a hole in one end. It turns out that they are fossilised brood cells (where the queen bee deposited her eggs) from bees that lived here back when this stretch of land across Africa that we call the Sahara desert was lush with grass and flowers. If you have the chance it is worth a visit. I would love to stay there for a week or decade, i have the feeling that time runs differently there.
