Firefighters Saturday snuffed a 20-acre grass fire near Ensign Peak trailhead that sent smoke billowing above Salt Lake City.

The fire was reported about 6 p.m. Saturday at the Ensign Peak Nature Park at 163 E. Ensign Vista Drive (1005 North), according to tweets from the Salt Lake City Fire Department. It was contained about 40 minutes later. The fire department said lightning was the most likely cause, and that a dry storm-cell passed over minutes before ignition.

The fire did not threaten structures. Flames were visible from downtown.

Firefighters evacuated the trail, a popular 1-mile hike overlooking the Utah State Capitol.
