A Type II team has taken over management of the 12,050 acre Big Hollow fire fifteen miles northwest of Carson and seven miles southeast of Cougar on the Gifford Pinchot National Forest.  Fire managers said Friday that Indirect control lines are being constructed with heavy equipment and roads to protect the communities of Cougar, Chelatchie and Yale to the west.  Structure protection is being implemented to protect cabins at Government Mineral Springs and the Carson National Fish Hatchery.  Firefighters are also assessing the risk to structures to the north and east in the fire area.  The Forest Service has issued area closures in the southwest portion of the Gifford Pinchot that include most developed campgrounds, dispersed camping, day-use and wilderness areas, and most forest roads and trails within the closure area.  The Washington State Department of Natural Resources has issued closures for the Siouxon Block and recreation sites within the Merill Lake Conservation Area.
