A 64-year-old woman died after the ATV she was driving landed on top of her.

Troopers responded to the crash at about 1:30 p.m. Saturday in Sanders County about three miles south of Heron on Hugh Lillard Road, according to the Montana Highway Patrol.

The woman left the road to go around a tree and when she tried to go back on the road, she lost control and rolled down a hill, that's when the ATV landed on top of her, Trooper Bryce Ford said.

The woman was not wearing a helmet, and she died at the scene, Ford said.

The woman's name is not being released at this time.

The cause of the crash is still under investigation.
