Tuesday, Park County emergency officials said the Weston Pass Fire was caused by lightning.
The fire is now 5 percent contained, but it burned an additional 3,000 acres Tuesday, growing to 9,342 acres.
Fire efforts were focused on the southern and southwest portions of the fire, with multiple fixed wing aircraft making several retardant drops to minimize spot fires and contain and spreading.
Approximately 484 fire personnel are currently working the blaze. Current resources include three Type 1 hand crews, 9 Type 2 hand crews, 14 engines, two dozers and six helicopters.
The main focus is now protecting the Campground of the Rockies Association (CORA), as it was put under mandatory evacuation Sunday.
CORA (Campground of the Rockies Association) is now under mandatory evacuation, Level 3. If you are in the area, leave immediately, as quickly as possible. Do not delay!
