Pot Farm Found in Park

A park service pilot on a routine flight over the North Cascades National Park service area helped discover a large marijuana farm worth nearly $48 million -- the first such grow operation found in a national park site in the state.

Officials said the farm, which law enforcement officials raided this week, contained more than 16,700 plants. It was well established and resembled the elaborate grow sites run by Mexican drug traffickers plaguing national parks in California, authorities said.
