On top of the cliffs at the great dry waterfall of Ásbyrgi, high above the ocean, the tide leaves its pools. The water comes with the rain, and the pools aren’t filled with crabs and anemones, but bog cotton will do.

It’s always a thrill to come across life thriving in hostile places, including here, trod upon by so many human travellers trying to get to the cliff edge without slipping over in the muck. Perhaps the bog cotton is thinking the same thing!
