The St. Francis Dam collapsed at 11:57 am on March 12, 1928. As such, due to reporting deadlines, the first reports of the disaster did not appear in most morning newspaper editions in Los Angeles and elsewhere in the country until March 14. However newspapers with evening editions such as this "Second Extra" edition of the Los Angeles Examiner were able to report on the dam break as early as the next day March 13.
