Arctic Plunge

The Arctic Plunge is a non profit organization consisting of volunteer members: Joni Sundeen, Sue Lysdahl, Shalisa Koehntopp and Jim Lundeen.

The ARCTIC PLUNGE was formed after Herb Knutson took the first ARCTIC PLUNGE into the frigid waters of Long Lake following the 9-11 attacks. The first plunge was held in February of 2002 raising $5,500.00 to benefit the Red Cross!
