The Brownstone Fire was detected on August 2nd. The fire is burning in the Bob Marshall Wilderness and was ignited by lightning on July 28th.
On the afternoon of Wednesday, August 15th, the Brownstone Fire was active in Brownstone and Cayuse drainages. The fire has spotted and is burning eastward in the head of Cayuse Creek, but it has not yet crossed onto the south side of the creek. The fire also made a run from the bottom of Brownstone Creek up the southeastern face of Brown Sandstone Peak.
The finger over the top of Brown Sandstone Peak and into the Sandstone drainage continues to widen, but has not rolled downhill much at this point. There are a few visible spots in the upper South Fork of the White River, but no growth has occurred.
Additional growth is expected going into the weekend. We will continue to monitor the spread of the fire with ground and aerial resources. Implementation of structure protection continues at Big Prairie Work Center.
Trail and area closures effective midnight on August 18th are pending for the Big Prairie area.
