WALLA WALLA -- A wildfire that burned about 34 square miles in Walla Walla County earlier this month was caused by people shooting a high-powered rifle, an official said today.
The Eureka Fire started Aug. 6 about 17 miles northwest of Prescott. It burned through wheat stubble, grasses and sagebrush between Lyons Ferry Road and the Snake River, destroying a machine shed and a shop facility.
Abbie VanDonge of the Walla Walla County Emergency Management office said investigators determined the fire was started by "one or two people out shooting a high-powered rifle." No charges have been filed at this time, she said.
About 185 firefighters from across the state, 40 engines and a helicopter were called in to fight the blaze. Firefighters were demobilized Aug. 9.
