"For centuries, sand has flowed down from the Sierra Nevada, moved through the Sacramento-San Joaquin Delta and washed into the Bay, where it was joined by sand from other rivers and creeks. Some sand stayed in the Bay and some washed out the Golden Gate. Currents carried the sand mostly south, where it helped build up Ocean Beach and beaches down the coast."
