Boulders from a rockslide are to blame for a crash that injured a woman in northern Minnesota over the weekend. 

According to the Minnesota State Patrol, a rockslide sent large boulders onto Hwy. 61 at the Silver Creek Cliff Tunnel along the North Shore just past Two Harbors. The crash happened Saturday around 6:20 a.m. 

The boulders caused a 2015 Honda Civic driven by a 60-year-old Two Harbors woman to roll. The woman suffered non-life-threatening injuries and she was transported to Lake View Hospital in Two Harbors for treatment. 

The Silver Creek Cliff Tunnel is 1,344-feet-long and was built in the early 1990s. It goes directly through the North Shore's highest bluff and was built to keep drivers safe from tumbling boulders and a steep cliff, according to Only In Your State.
