The U.S. Forest Service said lightning ignited a wildfire near Hassel Lake in the Boundary Waters. It is currently estimated at about 2 acres. 

Hassel Lake is about 10 miles northeast of Tower, Minn. It is west of Burntside Lake and Crab Lake. 

Firefighters report they flew over it Friday and saw "moderate fire activity." A plane made a few water drops.

The Forest Service says the area is away from any lakes or portages, so it's too difficult to access on foot. 

So far, one plane and one helicopter have been assigned to the fire. They'll continue to fight it from the air. 

Smoke from the fire could be seen from Highway 169/1 between Tower and Ely, according to the Forest Service.

On Saturday, the Forest Service announced closures of the following portage trails, lakes, and campsites which are posted closed as of 12:01 p.m. Saturday:
