A new wildfire in Grand County forced authorities to issue mandatory evacuation orders Wednesday evening. According to the U.S. Forest Service, the fire is burning on federal land north of Parshall and Kremmling. The Grand County Office of Emergency Management said the Big Horn Park area is under a mandatory evacuation order. Evacuees should go to the Kremmling Fairgrounds for accountability, GCOEM said. Authorities are calling the blaze the East Troublesome Fire. The Forest Service estimated the fire’s size at 100-200 acres. Officials said an air crew flew over the fire and determined it was inaccessible by fire engines. “Crews and aircraft from the Williams Fork and Middle Fork Fires will be on scene tomorrow morning,” officials said in an update Wednesday evening. The Colorado Department of Public Health and Environment said the fire is producing heavy smoke along East Troublesome Creek to the north of Highway 40 and to the east of Wolford Mountain Reservoir.
