Emergency crews rushed to a large mudslide in western Colorado in Mesa County Sunday night where three people may be missing.

The slide struck Sunday on Grand Mesa near the town of Collbran, about 40 miles east of Grand Junction, according to media reports.

The Mesa County Sheriff's office says there are reports of three people missing.

The Grand Junction Sentinel said both the sheriff's office and Collbran authorities have responded to the slide, which is along Salt Creek Road near Vega State Park.

Mesa County Lt. Phil Stratton told the Denver Post that the slide if very large.

The department said that the person who reported the slide at about 6:15 p.m. MDT "described hearing a noise that sounded much like a freight train."

Station KMGH-TV reports that a unified incident command has been established between Plateau Valley Fire Department and the Mesa County Sheriff's Office, to handle the slide and search for the people possibly caught in it.

Heavy rain has fallen in the area this weekend.
