BOULDER - When warm weather follows a week of cold, rainy and snowy conditions the likelihood of experiencing a rock slide is much higher.
On Saturday, several small, medium and large sized rocks tumbled down Berthoud Pass onto U.S. Highway 40.
Stephen Dorsey and his girlfriend were driving back to Denver from Hot Sulphur Springs and got swept up in the small slide.
"It was a little bit scary," Dorsey said. "It sounded kind of like a massive firework going off right underneath your feet".
Two rocks, the size of watermelons, slammed in to the side of Dorsey's car. One of them left a large dent on the passenger side of his vehicle.
"One of the big ones did hit a lady's car right in front of me and definitely messed up her wheel and tire. It was all bent in and stuff," Dorsey said.
The Colorado Department of Transportation says last week's rain and snow mixed in with this week's warmer temps, likely loosened the rocks up, forcing them to fall off the mountain side.
The moral of this story is a simple one: If you happen to be driving, keep your eyes on the road, but also make sure to keep your eyes on the surrounding area.
