An unexplained series of lights that have been appearing on Mitchell Flat east of Marfa, Texas for most of the last century, they are described as being the size of a basketball, floating in the air at around shoulder height, and sometimes moving rapidly in various directions. Although sightings are rare there is a large amount of photographic and video evidence. Skeptics, however, usually attribute them to traffic on US Route 67, or electric byproducts of quartz mining in the area.
