The mossy boulders of the Laki lava field are a favorite stop. The moss is thick and soft, covers the lava field and gives rise to other plants.
The moss is so thick & soft it's tempting to walk on, but doing so will crush and/or tear it. It takes 80 years for the moss to recover.
On one side of the waterfall called Svartifoss it was calm. On the other, the wind was blowing furiously.
