DENVER — The Lee Fire burning southwest of Meeker was downgraded in size Wednesday after fire officials said better mapping lead to a better estimate of the fire size.
On Monday, fire officials said the slow-moving blaze had burned 138,844 acres of land just a little more than three weeks after a lightning strike sparked the fire. By Wednesday, however, fire officials told Denver7 the acreage was adjusted back to 137,758 acres following improved mapping.
"The earlier increase was due to limitations in the previous data, which temporarily raised the estimate. With updated mapping now complete, the current acreage is 137,758 acres and reflects the most accurate information available," a spokesperson for the Incident Management Team currently battling the blaze told Denver7 in an email.
The updated acreage officially rolls back the Lee Fire to the fifth-largest in state history, and puts it just two acres shy of tying with the Hayman Fire, which burned 137,760 acres in 2002.
