Did you know? CORONADO’S GOLD SAND is caused by mica, a shiny silicate mineral found in granite and other rocks. It washes down rivers from the mountains of Mexico, ending up in the Tijuana River and running into the Pacific at the Tijuana River Estuary. Micafilled silt is picked up by the Silver Strand Littoral Cell, a circular current that flows from south to north along the coastline, traveling several miles south of the Mexican border to Point Loma and back out to sea. The current picks up the sediment from the river mouth and carries it up the coast, depositing it on Coronado Beach. ■ HAIKU Gold glittery sand Shiny and beautiful On Coronado beaches - Leslie Crawford
