A large wildfire is burning 50 kilometres south of Dawson City, Yukon, near the mouth of the 60 Mile River.

Fire officials believe a lightning strike sparked it. On Monday night, they estimated the blaze was 100 hectares in size and active due to dry and windy conditions.

Officials say it is visible from West Dawson, the Top of the World Highway and the Dome.

Wildland Fire duty officer Lorne Harris says five cabins and a small mining camp have been identified in the area.

He says the closest structure is about three kilometres from the fire.

Firefighters placed sprinkler kits on the nearby cabin.

Officials say they've been in regular communication with the mining camp owner.

The mining camp is located near 10 Mile Creek, approximately 10 kilometres from the fire.

Officials will be reassessing the fire this morning.

The Dawson fire was one of two reported Monday evening.

A 16 hectare fire is currently burning approximately 110 kilometres west of Beaver Creek in the wilderness zone with no houses or other infrastructure at risk.

Meanwhile, windy conditions are causing smoke from a large fire burning in Alaska to shroud the community of Beaver Creek. Officials say the blaze does not pose a threat to the community.

With temperatures expected to reach thirty degrees in some areas and scattered lightning expected this week fire officials are asking the public to only burn if absolutely necessary and to ensure any fires lit are completely extinguished before leaving them.

The public is also reminded that burning permits are now mandatory in the territory and will be suspended whenever the fire danger rating is moderate, high or extreme.
