The Red Shale Fire burning north of the Gibson Reservoir near Red Shale Creek and Gates Park in the Bob Marshall Wilderness has grown significantly over the past week, forcing several trail closures in the area.

Started by lightning on July 18, the fire burned 330 acres by July 20. The fire now covers 7,618 acres, burning in an area of downed timber and new growth in the perimeter of the 1988 Gates Park Fire . A helicopter is dropping water on hot spots near structures at Gates Park.

A change in the weather should help. The National Weather service is forecasting cool, wet weather by the end of the week. The following trails are now closed due to the fire:
