DURANGO — Investigators say beer was a factor in a rollover crash in southwest Colorado, but drunken-driving was not to blame.

Capt. Adrian Driscoll with the Colorado State Patrol says a pickup crashed after sliding on a pile of beer mash that had spilled on state Highway 172 near the Durango-La Plata County Airport on Thursday morning. Mash is a byproduct of beer brewing, and local breweries often give it to ranchers to feed their livestock.

The pickup driver suffered minor injuries, and a passenger was taken to a hospital with moderate injuries.

Lisa Schwantes, a spokeswoman for the Colorado Department of Transportation, tells The Durango Herald that a snow plow had been sent to clean up the slippery mess but did not get there in time.
