Canada

The sun is just a dim red dot. The nearby Canadian Rockies are shrouded in thick wildfire smoke.

Bob Gray knows we probably shouldn’t be hiking up a mountain right now.

“I have a scratchy throat,” he says. “Physically it effects my breathing. I probably shouldn’t spend a lot of time in it.”

Back in 2012, one of the major employers in Montrose, Colorado, a sawmill, was in receivership and on the brink of collapse. At the time, local media reported that the cost of logging timber had become prohibitively expensive, and the log yard was nearly empty.  

These days, logs are stacked high next to a humming mill. Production is up 20 percent from even just 2016.

Haze from smoke drifting south from wildfires burning in Canada continues to linger over Colorado, prompting the state's health department to issue a wildfire smoke health advisory for much of the Front Range. The advisory includes El Paso, Pueblo, Huerfano, Las Animas and Otero Counties, and is set to expire at 4 PM Wednesday. (UPDATE: The advisory has been extended until 9 AM Thursday.)
