Late summer and fall is historically one of the most active times of year for wildfires, and it could be worse this year with severe drought conditions.
After a long stretch of smoke earlier this month, it looks like it may return this week. The good news is it won't be nearly as bad as our first round - here's what to know.
Wildfires can spread undeground, creating dangerous ash pits that firefighters or hikers can fall into. Normally it doesn't happen, but with dry conditions it's occuring in the Lake Superior National Forest.
