Wildfire smoke continuing to slow Caribou fire

LIBBY, Mont. — The silver lining of the cough-causing wildfire smoke covering Lincoln County is that it is helping limit the growth of the very wildfires that are causing it. In the northern part of Lincoln County, a fact sheet released Thursday morning said the day-over-day increase of the Caribou fire was only 646 acres — from 19,985 to 20,631.
