Fire crews continued mop up work on the Eagle Creek fire near Lame Deer with containment up to 75 percent by Wednesday night, said Pat McKelvey, information officer.
Acreage increased by only 10 acres, to 4,150, McKelvey said. “They had a good day,” he said.
There was a lot of cloud cover and temperatures were cooler later in the afternoon, he added.
The human-caused fire started Saturday in the Black Eagle Creek drainage about 11 miles south of Lame Deer on the Northern Cheyenne Reservation. The fire burned through grass and timber, but no structures were threatened.
The northern edge of the fire is burning in an area that had been logged and where there were big slash piles, which normally are burned later when there is snow, he said.
On Wednesday, there were 144 people on the fire and at least 15 engines and other equipment.
The forecast for Thursday called for slightly cooler temperatures with a high of 79 degrees and higher humidity of about 22 percent to 27 percent, McKelvey said.
