The nearly 4,000-acre Old Trails fire sparked north of Airway Heights and jumped the Spokane River. That and two other fires in Spokane County forced 60,000 evacuations, threatening more than 14,000 structures within the city’s evacuation boundaries.

The flames spread easily in 35-45 mph winds, tearing through Riverside State Park and razing at least 640 structures as of Sunday, mostly within the city. Many of the lost homes were identifiable only by the chimneys left standing.
