The fire prompted officials to close San Juan National Forest.

The forest, which covers more than 1.8 million acres in western Colorado, announced the closure is intended “to protect natural resources and public safety.”

“Under current conditions, one abandoned campfire or spark could cause a catastrophic wildfire, and we are not willing to take that chance with the natural and cultural resources under our protection and care or with human life and property,” said Richard Bustamante, SJNF forest fire staff officer.

Anyone caught violating the closure, SJNF said, could be punished with an individual fine of up to $5,000 or $10,000 for an organization, a six-month prison sentence or both.

Graham said earlier that 2,162 structures or homes have been evacuated since the beginning of the fire, and 500 residents are currently on pre-evacuation.

The other West Coast wildfires

The 416 Fire was one of several West Coast wildfires that began around June 1.

The Ute Park Fire in New Mexico began May 31 and forced 2,200 people in the area to evacuate their homes within the first three days of the blaze.

The wildfire was 92% contained on Wednesday, though Cimarron Canyon State Park would remain closed through July 8, according to InciWeb, a federal database of US fires. The Ute Fire has burned 36,740 acres.

No homes had burned, but 14 outbuildings have been destroyed.
