The Bureau of Land Management is offering a $2,500 reward for information leading to the arrest and conviction or civil prosecution of those responsible for the 287 acre Pyramid Fire that started June 3.  The fire was about a mile south of Pyramid Lake in the Painted Hills Range, about 2 miles north of Mullen Pass.  It was started by target shooters who fled the area without reporting it, the BLM said.  Anyone with information is asked to call the BLM at 775-885-6117.
