Even the Great Lakes are prone to dangerous currents that can threaten experienced swimmers.

PARK TOWNSHIP, Mich. Two men have been rescued from Lake Michigan after they were caught in a rip current while swimming. The 34-year-old and 32-year-old men were at Holland State Park in western Michigans Park Township early Sunday evening when they were swept into deeper water, according to the Ottawa County sheriff's office. A jet ski operator was able to get one of the men to a pier where bystanders began cardiopulmonary resuscitation. Another jet ski operator was able to take the second man to a beach where he was evaluated by paramedics. The sheriffs office said a no-swimming notice was posted at the state park where three people have drowned this year.
