He says on his Vimeo page: “High plains storms are some of the most beautiful and wild in the world. I spent May – September 2014 photographing all types of severe weather in Wyoming, Montana, South Dakota, Nebraska, and Colorado. This time lapse project is a result of that effort. From rainbows to tornadoes, there is a little bit of everything in here.”
