A mudslide estimated to be two miles wide, four miles long, and 250 feet deep swept through Grand Mesa in Colorado Sunday night. Three men are still missing after it struck east of the small town of Collbran with the first reports coming at around 6:15 p.m. Sunday night. Mesa County sheriff Lt. Phil Stratton said "This slide is unbelievably big," and the area is still unstable. Authorities believe heavy rain contributed to the mudslide. Officials will inspect the mudslide by air in the hopes of finding the three men, who have not been publicly identified but are locals.
