Now that Fourth of July festivities have ended for 2017, volunteers headed back to San Diego area beaches Wednesday, to help clean up.
It's estimated more than half a million people visited beaches in the City of San Diego over the holiday weekend.
Lifeguards with the San Diego Fire-Rescue Department (SDFD) performed more than 500 rescues and medical aid operations during that time.
Among the rescues, lifeguards helped three people trapped by high tide in the La Jolla area.
The Surfrider Foundation of San Diego County, San Diego Coastkeeper and I Love a Clean San Diego helped to pick up debris people left behind in Mission Beach, Ocean Beach, Crystal Pier in Pacific Beach and Oceanside Pier.
Organizers said last year, several hundred volunteers gathered up to 1,400 pounds of trash, and nearly 400 pounds of recycling material.
