Hunting Marfa Lights reports the results of an eight-year investigation (2001-2009) into mysterious lights seen near Marfa, a small West Texas town. This is, to date, the only long-term, extensive study of these phenomena. Reports of unusual lights east of Marfa extend back to the 1800s. Based on data collected, the author finds that while most of the observed lights in this area can be explained, about 3 percent are truly mysterious and of unknown origin. In addition to frequent on-site observations and photography, the author installed three automated monitoring stations equipped with a total of nine cameras, to collect nightly video records. Included in this 311-page book are 34 firsthand accounts from eyewitnesses and more than 120 illustrations and photographs. Of particular interest are compelling stories told by people, including the author, who have encountered these mysterious lights and have been astonished and amazed by the experience.
