UPDATE 5:30p 2/6: Work has resumed at southeastern New Mexico's nuclear waste repository. But officials say they don't yet know what caused the truck fire that forced an evacuation of the underground site.
A spokesman says an investigation will be conducted at the Waste Isolation Pilot Plant, where low level waste from the nation's nuclear weapons plants is stored in salt beds.
The site was evacuated and six people were treated for smoke inhalation after a truck hauling salt caught fire Wednesday.
Biologists are trying to save a threatened trout species in southwestern New Mexico, even as crews around the West struggle to contain blazes that have charred hundreds of square miles of forested countryside.
