These ruins in Canyon de Chelly, Arizona are called The White House, named after the lighter coloured dwelling you can see behind the darker buildings in front. These are ancient aboriginal houses high up on the cliff, presumably for security. It's a bit of a hike down to the ruins. I got a sunburn but it was worth it.
Prior to getting an infrared converted camera I was using a filter that I would screw onto the lens of my regular camera. Doing it this way caused exposures to be about 20 to 30 seconds long. Hence the streaking clouds. It worked out well as they became an important part of the image.
Taken at Boulder Bay on the shore of Lake Winnipeg, Manitoba, Canada.
