Two Nevada firefighters remain hospitalized with severe burns they suffered when flames burned over their engine while responding to a wildfire that started after a helicopter crashed 15 miles north of Battle Mountain over the weekend. The Sheep Creek fire has burned 89 square miles of sage brush and cheat grass since starting Saturday afternoon. The volunteer firefighters from Battle Mountain, Bart Negro and Damon Spring, were responding to the blaze when the fire engulfed their engine, leaving both with second- and third-degree burns.
