Authorities say Mosley told them he didn't think it was illegal to hike naked in a public forest.
Deputies report two women complained, saying they were confronted by a naked man, who offered to snap their pictures.
Mosley, who's from St. George, Utah, is now charged with indecent exposure.
Authorities say they're looking for people who might have encountered the naked man.
