Heavy smoke obscures the region around Yellowknife, Canada, in a new satellite image of wildfires that have choked the air and confined residents indoors.

Yellowknife sits on the banks of the Great Slave Lake in Canada's Northwest Territories. The fire season in the Northwest Territories has been harsh this year, with 284 fires reported so far, according to the region's Environment and Natural Resources Forest Management Division. More than 2.6 million acres (1,065,410 hectares) have burned. (In January 1978, the Soviet nuclear-powered spacecraft called Cosmos 954 fell into the Northwest Territories, scattering radioactive material from the Great Slave Lake into northern Saskatchewan and Alberta.)

The fires have not threatened the city directly, but their smoke has caused road closures and air quality problems, according to the Northern Journal. Supply trucks and residents trying to get in and out of the city have to wait for temporary wind shifts that lift the smoke, allowing enough visibility to drive. Highway 3, which connects Yellowknife to nearby towns and other highways, was closed until further notice, according to the territory's Department of Transportation.
