Two paddlers are missing after two canoes went over a waterfall in the Boundary Waters Canoe Area Wilderness (BWCAW) on Saturday, according to the St. Louis County Sheriff's Office.

The U.S. Forest Service closed parts of the Boundary Waters near the search site overnight Monday.

On Saturday around 7:20 p.m., a caller reported the canoes went over Curtain Falls, a waterfall between Crooked and Iron lakes on the Minnesota-Ontario border. The caller said two people were missing and at least one other person was badly injured.

After midnight, a Department of Natural Resources helicopter extracted an injured person and one person who was unhurt.

On Sunday, the St. Louis County Rescue Squad resumed search efforts for the two missing people.
