One person was killed and 30 people were taken to three hospitals with injuries in a pileup on Interstate 25 as a group of heavy snow tore through Denver on March 1, 2014. Local police said a total of 104 vehicles were involved in a string of accidents between Logan Street and University Boulevard that occurred as the heavy snow moved through town before 11 a.m.

“People were just driving too fast for conditions,” said Darrell Barber, whose Chevy Tahoe was hit repeatedly during the chain of crashes. “It was totally preventable.”

According to the Denver Post, Denver only received a total of 0.75 inches of snow the morning of the huge crash. I’m no meteorologist, but isn’t that an extremely small amount of snow? Check out the photo below to see what kind of damage 0.75 inches can really do.
