Civic leaders preview the 80-foot-wide waterfall at the Fort Moore Pioneer Memorial in downtown Los Angeles on this day in 1954. The memorial marked the site of a U.S. military fort constructed during the Mexican-American war. The waterfall, located off Hill Street between the 101 freeway and Cesar Chavez Avenue, has been dry since a 1977 drought.
