RICHLAND, Wash. - Hundreds of pot plants were discovered in Richland.
The marijuana is worth almost half a million dollars on the street according to police.
Police report that they were found just north of Columbia Park Trail and west of highway.
Richland police said they periodically check this area because they have found people trying to grow pot there in the past.
Authorities have the plants as evidence and some are 10 feet high.
Benton County Sheriffs, the Drug Task Force and Richland Police all worked together on this case.
Police said this area is ideal for marijuana growth because there is a lot of sun, soil, and water.
Deputies said they have not seen a marijuana bust this big since last year.
Richland Captain Randy Barnes said, "We've certainly stopped 450 plants from making it onto the streets and somebody put a lot of effort and work into that and now that is gone and we are still looking for the suspects."
Police are searching for the people responsible for harvesting the plants.
