Flames tore through a three-story house in Boulder County early Thursday morning.
It happened on Lefthand Canyon Drive.
The flames were just too strong and Boulder County firefighters told us they had to let it burn.
Getting close enough to fight the fire would have been too dangerous.
Luckily, no one was home when the fire started overnight. Boulder County officials say they're still trying to determine how the fire started, but they can confirm the home is a total loss.
Traffic is currently blocked at approximately 1000 Lefthand Canyon Drive keeping vehicles from traveling westbound up Lefthand Canyon Drive. Eastbound traffic is blocked in the area near the intersection of Lefthand Canyon Drive and Olde Stage Road. That's due to the large number of rescue personnel and vehicles on scene.
