This is one of the many waterfalls you can find everywhere on Iceland. This one is called Gjáinfoss and is located in a wonderful valley called Gjáin. You can see more photos taken in that valley in a post I wrote a few weeks ago.
Nevertheless, I picked this photo from my archive for this MMC. It’s Gjáinfoss on Iceland. I took that image on July 1st, 2014. One year ago.
Btw. as always: click on the photo to see it in a higher resolution
