Officials say several thousand tons of mud and debris have come down the Missionary Ridge mountainside near Durango in the past couple of days.
The Durango Herald reports up to 10 feet of mud, silt and rock have buried East Animas Rd. as a result.
The road has been closed since Friday.
La Plata County Office of Emergency Management Director Butch Knowlton says three drivers tried to get around the barricade on East Animas Road but immediately became stuck.
Five to 10 homes sit below the rockfall area, but none was in immediate danger as of Tuesday.
