(KRON) — California State Parks, which manages more than 340 miles of California’s coastline, is asking the public not to collect any sea glass, agates or other rocks found at state beaches.

Although the state has a rich history of rockhounding, and allows beachgoers to collect a limited amount of rocks or minerals per day, California State Parks is encouraging the public to “leave no trace.”

“California State Parks’ mission is centered on the protection of the state’s natural and cultural resources for the enjoyment of current and future generations,” California State Parks told KRON4. “As such, we encourage visitors to ‘leave no trace,’ and generally do not promote the collection or removal of natural resources, including items like agate or sea glass, from park lands.”
