Ryan Peterson (right), firefighter with the Bureau of Land Management Weaver Mountian Station, is one of about 50 personnel working Saturday on prevention measures at Wickenburg Municipal Airport in preparation for Fourth of July fireworks. U.S. Forest Service hotshot crews from San Juan (Durango), Colo., and Groverland, Calif., and local BLM crews coordinated with Wickenburg Fire Chief Ed Temerowski to form a fire break in case of fireworks landing in the dry brush, according to Weaver Mountian helitack crew member Chandler Goering. The agencies cleared brush, cut tall grasses and scratched a fire line. “Prevailing winds come from the southwest, so to ease our minds and the minds of the public we are making a firebreak, so if we get an ignition source out here we can get around it quickly,” Goering said. BLM and WFD have coordinated fire protection for the local fireworks show for more than a decade and will have crews staged at the airport Thursday evening. The hotshot crews may have moved on by then, depending on whether they have received an assignment, Temerowski said.
