A massive pileup that snagged 104 cars on a Denver interstate highway Saturday killed one person and left 30 others injured.

The crash occurred on a two mile stretch of the Interstate 25 after a quick, heavy snow caught drivers unprepared. The northbound lanes of the highway had to be closed for several hours, reports The Associated Press. The lanes have since been cleared enough to be reopened.

The snow was from the storm that has been pounding California for the past couple of days. National Weather Service meteorologist Jim Kalina said, "We're on the front leading edge of it, so there's some moisture coming up."

One driver spoke with Denver News 7 and said, "It literally just whited out and my brakes weren't stopping [the car]. And then all of a sudden cars just started hitting everybody."

The one fatality was a passenger whose car hit the back of a semitrailer and the roof of the car was torn off. The driver survived the car crash.

To combat the poor road conditions, several tankers were brought in carrying fluid to help deice the roads for drivers.

Colorado Department of Transportation said that wave escorts were being used during the poor weather conditions to help keep traffic moving at a reasonable and safe speed.
