A woman was seriously injured and three others also were hurt when the vehicle she was driving rolled off KM Ranch Road north of Kalispell early Saturday.
According to the Montana Highway Patrol, the woman drove her vehicle off the left side of KM Ranch Road near Twin Bridges Road at about 3 a.m., striking a boulder that caused the vehicle to roll. It then struck several standing trees.
The woman and a man riding in the front passenger seat were ejected during the crash, while two men in the back seat were wearing seat belts and were not ejected.
The crash was reported at about 3:40 a.m. and the Highway Patrol arrived at the scene at about 4 a.m.
The woman and a man were transported by ambulance to Kalispell Regional Medical Center, while the other two passengers were transported to North Valley Hospital in Whitefish.
The Associated Press reports that the woman has since been transferred to a hospital in Seattle.
According to the Highway Patrol, alcohol was a factor in the crash.
