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.
