Authorities say crews are searching Lake Michigan for a missing teenage girl after a large wave knocked her and another person off a pier along western Michigan

HOLLAND, Mich. -- Crews searched Lake Michigan on Thursday for a missing teenage girl after a large wave knocked her and another person off a pier along western Michigan and she couldn't get out of the water, authorities said.

The Ottawa County Sheriff's Office said two people were on the pier at Holland State Park on Wednesday night when they were struck by the wave. One climbed out of the water and sought help, but the other was presumed missing.

Waves at the time were estimated at about 12 feet (3.7 meters) high, the sheriff's office said. The search was described as a recovery effort early Thursday.

The person who got out of the water was identified as a male. His name and the identity of the missing person weren't immediately released.

Crews from the sheriff's office, the Park Township and Holland fire departments, and the U.S. Coast Guard were among involved in the search.
