       The U.S. Forest Service announced Friday that Colorado’s second-largest wildfire on record was human-caused.

       "Given the location and time of year that the fire started, it may have been caused by a hunter or a backcountry camper, and possibly by accident," the Forest Service said in a news release, adding that the investigation is ongoing.

       The agency said it is still unclear how the East Troublesome Fire started, but that the determination was made based on evidence gathered at the origin of the blaze.

       The fire was reported on Oct. 14, 2020, about 15 miles north-northeast of Kremmling.

       Windy and drought-stricken conditions in Colorado allowed it to spread, coming dangerously close to the town of Estes Park near Rocky Mountain National Park.

       The fire was slowed by a late-October snowstorm, but only after more than 350 homes were destroyed.
