For the past eight months, I have been finding, photographing and removing (except for the washing machine) man-made detritus from Usery Mountain Regional Park, a 3,600-acre desert area east of Phoenix and adjacent to the Tonto National Forest. Why do this? First, I find these objects -- everything from a paperback of "Of Mice and Men" to rusted cans and broken china to golf balls -- to be fascinating, imbued with a story of how they came to be there and how the passage of time has worn them. While I find beauty in just about all the objects, they do not belong in this otherwise pristine sliver of Lower Sonoran Desert. Each time I remove an object, I feel I've made that part of the world just a bit better for the hiker, horseback rider and mountain biker that follows in my path.
