This was taken somewhere along the Ring Road in Iceland. If you are into waterfalls then Iceland is the place to be; there are hundreds of them. Not to mention all the otherworldly scenery that has made this country very popular with photographers; black sand beaches, puffins, ice caves, northern lights, etc.
This is about a one second exposure of sand falling off a ledge in upper Antelope Canyon near Page, Arizona. This canyon, both the upper and lower section, is one of the most amazing places that I've seen on my travels; more enjoyable than the nearby Grand Canyon. It was a bit of a feat to get this shot as there were tourists all over the place.
