Summit Fire & EMS dispatched a three-person crew to assist with battling the wildfire that started along Interstate 70 on Thursday, Sept. 7, in Eagle County, according to a Facebook post from the fire protection district.

The Eagle River Fire was originally started by a vehicle crash on U.S. Highway 6 that ignited dry grasses in the area. The fire closed nearby sections of Interstate 70 for several hours and U.S. Highway 6 overnight last week.

The Summit Fire & EMS crew reportedly responded to the fire under the Mountain Area Mutual Aid agreement. Under the agreement, fire departments throughout the central mountains will rush to each others’ aid for up to 24 hours for an immediate attack, Summit Fire & EMS said in the Facebook statement.

At the height of the emergency response, 10 fire engines, two hand crews, a single-engine air tanker and a helicopter attacked the fire, according to the Eagle River Fire Protection District. The 27-acre fire was declared under control by the next day.
