For months, remnants of last summer's destructive Alkali Lake wildfire have been smouldering underground in northwestern B.C. An image posted by former minister of Indigenous Services Jane Philpott shows some of the damage caused by the 2018 Alkali Lake fire. When wildfires burrow underground, there's not much crews can do to manage them apart from watching and waiting for them to burn themselves out, according to Gray. The good news is that underground fires smoulder over relatively small areas compared to wildfires at the surface. But as the climate continues to change, there's a growing likelihood that vestiges of one summer's wildfires will wait out the winter underground and appear again the next year.
