Sheriffs started this burn early about an hour before they had planned too.
The reason for that is to try and get people back to their homes as quickly as possible.
He did hear a few small pops from this distance that could have been a few left over explosives but, according to the bomb squad this fire will destroy the over 150 to 200 pounds of explosives left at the site.
Now they are expecting the fire to smolder for another few hours before they fully put it out.
This area is still evacuated and the roads are closed at this time to residents.
Spencer will be live all afternoon to bring you the very latest in Happy Valley.
