Last night’s Boise sunset featured a sullenly glowing red sun, looking more like a Los Angeles sunset than an Idaho one. Here’s a news item from the Associated Press suggesting the cause was far-off fires in Khakassia, a region in southeastern Siberia: PORTLAND, Ore. (AP) — The National Weather Service says wildfires in Siberia are to blame for haze hanging over much of the Pacific Northwest, giving sunsets a red hue. Forecasters in Portland expect the smoke to dissipate Monday, which is expected to be another warm and sunny day. Large fires burning in Khakassia, a region in southeastern Siberia, were started by farmers burning the grass in their fields. They spread out of control because of strong winds, killing more than a dozen people and destroying hundreds of homes.
