Photographer Marc Muench from Santa Barbara, California, has travelled close to a million miles across the highways of the US over the course of his 25-year career capturing the wilderness of the USA as yet untouched by human development.

Marc is only too aware of the fragility of the American wilderness. He hopes that through his photography he can raise people's awareness of just how beautiful the wild can be. "For much of the recent past most of America was undeveloped, unexplored and still wild," he said. "This vast wilderness is quickly becoming tame with development pressure and expanding populations. Increased demand for resources plays the most damaging role in taming the wilds of the American wilderness."
