Authorities say the marijuana on Arroyo Camada Beach had a street value of $4 million.

About 2,000 pounds of marijuana worth an estimated $4 million was scattered in bales on a beach near Santa Barbara, Calif., on Sunday after a drug smuggling boat washed ashore.

The bales were found on Arroyo Camada Beach, near Refugio State Beach. The 30-foot panga boat — an open, outboard powered boat — was found on the shore, equipped with about 20 fuel containers.

The 50 bales of marijuana have an estimated street value of about $4 million, according to the Santa Barbara County Sheriff's Department. The drugs were found partially hidden in bushes near a road leading from the beach.

About 20 panga-style boats have landed on the Santa Barbara County coastline during the past two years. The boats are commonly used to transport drugs and other contraband.
