Though “originating in the vicinity of the south wilderness and the land of Manti (Alma 16:6; 22:27),” the river Sidon “apparently flowed north to the sea, passing just east of the city of Zarahemla (Alma 3:3; 6:7; 44:22). The river is mentioned most frequently as a landmark and strategic site in military confrontations” (Largey, Book of Mormon Reference Companion, 723).
