According to Wheat Ridge Police Department Lieutenant Mark Cooney, the culprit was a vehicle belonging to EDS Waste Solutions in Golden.
Not that "waste" is necessarily the best description of what spilled. Cooney notes that officers will be meeting with the driver at around 11 a.m. this morning to get more details. But at this point, they believe it was "some sort of organic soil."
Cooney adds that the driver will be cited for the incident, which led to a crash involving eleven separate vehicles (no serious injuries were reported) and the transformation of the roadway into a still life.
Update, 12:59 p.m. October 4: The EDS Waste Solutions driver who allegedly spilled organic soil on I-70, prompting an eleven-car crack-up, has been identified by the Wheat Ridge Police Department as Victor Ward of Arvada. He's been cited for Spilled Load on Highway (yes, that's the actual violation name). The case comes before Wheat Ridge Municipal Court on November 9.
