On September 16, 1928, a hurricane came ashore near the Jupiter lighthouse and traveled west across Palm Beach County to Lake Okeechobee, destroying hundreds of buildings and causing millions of dollars in property damage. Many of the 1,800 to 3,000 fatalities occurred when the Lake Okeechobee dike collapsed and flooded the populated south side of the lake. Approximately 1,600 victims were buried in a mass grave in Port Mayaca in Martin County; in West Palm Beach, 69 white victims were placed in a mass grave in Woodlawn Cemetery and approximately 674 black victims were buried in a mass grave in the city's pauper's burial field at Tamarind Avenue and 25th Street, while many others were never found. On September 30, 1928, the city proclaimed an hour of mourning for the victims, with memorial rites conducted simultaneously at each burial site. Two thousand persons attended the ceremonies at the pauper's cemetery, where noted black educator and activist Mary McCleod Bethune (1875–1955) read the mayor's proclamation. This burial site was not again recognized until 1991, when a Yoruba (Nigerian religious) ceremony was held here.
