You can just see the Reykjanesviti lighthouse in the steam comming from the mud geyser Gunnuhver. The mud geyser Gunnuhver is the largest mud geyser in Iceland. When this picture was taken the air was farily cold so a lot of steam was comming from it and you realy could not see the geyser itself.

At the right end of the picture you can see the begining of a walk path that leads to Gunnuhver but all that could be seen there was steam so I don“t have a picture of it.
