SPOKANE, Wash. - Spokane Fire officials say Wednesday's brush fire on Beacon Hill may be the latest in a string of what may be intentionally set fires."Specifically today with the Beacon Hill fire, when we know there's no lightning, a blue sky, and no power lines nearby, there's a high level of belief that it was a purposefully set fire," Assistant Fire Chief Brian Schaeffer told KHQ.It's the second brush fire in our area in two days. Another broke out near the Washington-Idaho state line Tuesday evening at Trent & Idaho. The exact causes of both fires remain under investigation.However, a definitive example of arson can be found at the totem pole off Northwest Boulevard in the Audobon neighborhood in North Spokane. Schaeffer confirmed to KHQ that someone has set it on fire twice over the summer using accelerants.We're not out of the woods yet with our fire season. Despite this cooler weather, Schaeffer says fuels are just now drying out, and this could be the pinnacle of the season. The fact that people may be intentionally setting fires, on top of an already busy season for firefighters, doesn't help."It's very troublesome because when we do have this dry season, we do have these winds, it doesn't take a lot to become catastrophic," Schaeffer added. "Nobody in this community wants to see another Valley View, another Firestorm."
