Authorities investigating the cause of Colorado's most destructive wildfire zeroed in on a fire pit the day after the fire broke out.
New details about the probe into the fire in the foothills near Boulder were included in documents released Thursday by the sheriff's office.
The Denver Post reports that the first clue came Sept. 7 as an investigator took photographs of the area where the fire started and felt heat against his back. He turned around and found the remains of a fire pit on the property of a volunteer firefighter. An infrared thermometer showed temperatures of up to 1,000 degrees.
According to the documents, the firefighter, George Fairer, couldn't explain why it was so hot. He said the fire was cold to the touch when he put it out.
