Craig Arnold was a professor at the University of Wyoming. He cited Ani DiFranco as a muse and claimed he was more interested in art made in moments of happiness than art made to be beautiful. On April 26, 2009 Craig Arnold went missing on the island of Kuchino-erabu. He was in Japan to work on a lyric book about volcanoes. May 8, 2009 a search and rescue team concluded he suffered a leg injury and fell to his death on a steep cliff. According to his partner of six years, Rebecca Lindenberg, "he did not wait or wonder or suffer."
His first collection, Shells won the Yale Younger Poets selection. His follow-up, Made Flesh was critically acclaimed.
