A wildfire that has shut down the North Unit of Theodore Roosevelt National Park tripled in size on Easter during another day of record heat and dry, blustery conditions in western North Dakota.
Meanwhile, crews on Monday fully contained a fire in the area of the park's South Unit that prompted the evacuation of the tourist town of Medora last Thursday.
Crews worked through the night on the North Unit fire -- dubbed the Horse Pasture Fire -- trying to get a handle on the blaze that is now 3,000 acres, or more than 4 ½ square miles, according to Beth Hill, acting outreach and education manager for the North Dakota Forest Service.
