IRON MOUNTAIN, MI -The most U.P contest ever has returned to Michigan's Upper Peninsula.

The "Car Plunge Contest" is hosted by the Rotary Club of Iron Mountain - Kingsford. For $10 you can make three guesses as to when a bright orange 1998 Saturn sedan will sink through ice and fall into a local caved-in mine called Chapin Pit.

The person who most accurately guesses the month, date, and time the car sinks will win $1,500. This is the fourth year the club is hosting the contest which benefits local projects supported by club membership.

Bets can also be made online here. Participants must be at least 18 and must make their bets by March 15. In the event the car plunges prior to the deadline, any entries submitted one day prior to the actual plunge date will be rejected and money refunded.

If no entry exactly matches the date and time, the winner will be determined by the entry that is closest to the exact date and time.

In the event of a tie, the prize will be split equally between the winners. Winners will be notified by May 1.

The car is the same that has been used in previous years. It has been altered to be environmentally safe by students at the Dickinson - Iron Technical Education Center.

The engine, transmission, power train, battery, radiator, fluid coolers, master cylinder and heater hoses have all be removed.

As have oils, greases, road grime, and other unintended vehicle contaminates. The Saturn was also painted and lettered by students and it will be removed using donated equipment once it falls through the ice.
