SANTA CRUZ, Calif. -

The ocean advocacy group Save Our Shores is calling Sunday's North Coast Cleanup Day a success.

39 volunteers helped clean five beaches in two hours. 421 pounds of trash was collected. The most common items found were food wrappers and cigarette butts.

Volunteers also found a tent frame, a large pair of purple underwear, and over 30 Styrofoam plates at Bonny Doon Beach.

North Coast Cleanup Day focused on Davenport Main, Panther, Bonny Doon, 4 Mile, and Shark Tooth beaches.

Panther Beach was the dirtiest site, with more than 125 pounds of waste. Sharks Tooth Beach came in second, with 82 pounds of trash.

Save Our Shores partnered with Diversity Center, State Parks and Santa Cruz County.

The next clean up day will be on July 27 and August 24, from 9:00 am - 11:00 am.
