Over 30 cans of marijuana were shot into Yuma, Ariz., using a cannon, Customs and Border Protection officials said Tuesday.
The suspicious cans were discovered near the Colorado River in Yuma on Friday.
Border Patrol agents said the discovery was "another unique but unsuccessful attempt" to smuggle drugs into the U.S.
An investigation of the area determined that the cans were fired from about 500 feet away with a pneumatic-powered cannon. A carbon-dioxide tank was found nearby.
Mexican authorities were also looking into the incident.
The marijuana weighed 85 pounds and was valued at $42,500. It will be destroyed, according to a statement from the agency.
