November 12, 2018 - Snow in Coast Mountains

Snow in Coast Mountains

On November 7, 2018, the Moderate Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a true-color image of a cold autumn day in southwestern British Columbia, Canada.

Snow coats the rugged Coast Mountains, delighting skiers who flock to resorts on mountains such as Whistler and Blackcomb. The coating of snow also brings welcome relief from a summer that was – literally – scorching. By August 29, the British Columbia government reported that the 2018 wildfire season had become the worst single fire season on record. There were 534 fires actively burning across the province on that date and 12,984 square kilometers (129,840 hectares) had gone up in flames. Exhaustive firefighting efforts, cooler temperatures and early precipitation brought an end to the widespread blazes. The snow cover and continued cold weather has helped reduce fire risk.

As of November 10, a few wildfires still continue to burn in British Columbia. The smoke from these wildfires (as well as from prescribed burns recently set and used to manage fire risk) can be seen as a gray haze in parts of the atmosphere particularly on the northwestern edge of the image. Several red hot spots – which mark actively burning fire in this image – are also visible. The BC Wildfire Service reports that as of that date that 1,351,314 hectares (13,513.14 square kilometers) of land had been burnt in the 2018 fire season.
