Jim Denevan recently made the world's largest freehand drawing on a dry lake in Nevada. How big is it? Three miles across. Jim walked for eight days, about 100 miles to draw the pattern. The drawing was transient, as all of Jim's work is: "It was completely erased in a rainstorm the next week... It felt strange to work so hard and not see tide come in. But rains did come which is sort of the same thing."
More amazing landscape sculptures and photographs at his website. San Francisco's KQED has a nice profile of Denevan.
The photographer who helped Denevan document his work in the Black Rock Desert, David Sievert, was honored by the Professional Aerial Photographers Association on Tuesday for his outstanding work. The story is here.
