May 29, 1937: The original Los Angeles Times caption reported:
This black roller dust storm is rushing toward Clayton, New Mexico. It was one of worst ever to strike that portion of southwestern dust bowl. A moment after this picture was taken the city was in darkness. The storm lasted several hours and was followed by rain. The interiors of houses were coated with dust and the outsides with mud. This picture was taken by an amateur photographer who happened to see the storm coming.
This photo was published in the May 29, 1937, Los Angeles Times.
According to an article on the New Mexico Museum of Art website, the dust storm that hit Clayton was 1,500 feet high and a mile wide.
