An underground coal fire recently discovered near the western Colorado town of Silt is venting smoke and fumes through two holes in the ground. No damage has been reported and the temperature near the surface is not high enough to start a vegetation fire yet, but state reclamation workers began filling the holes with dirt this week.
In 2002 an underground coal seam fire started a fire near Glenwood Springs, Colorado which destroyed some structures about 15 miles east of Silt.
