SPEARFISH (AP) -- Fire officials say crews have made significant progress on the Crow Peak Fire, which has been burning in the Spearfish area since the weekend.
The fire in western South Dakota's Black Hills National Forest was sparked by lightning over the weekend. It remains at about 130 acres, but is now 65 percent contained.
About 170 people are fighting the fire. Firefighters on Wednesday continued to strengthen and reinforce control lines around the blaze. Mop up efforts have begun on the north and east side of the fire.
Officials say three firefighters were treated for dehydration on Tuesday, but cooler temperatures provided some relief to the firefighters on Wednesday.
