Despite the freezing temperatures, about 140 Mat-Su Valley residents decided to take the plunge Saturday at Lake Lucille.

The cool dip was all part of the 9th annual 2013 Mat-Su Plunge.

Everyone involved raised money earmarked for local non-profits around the Valley.

The Matanuska-Susitna Borough Emergency medical services were nearby to lend a warm helping hand.

Organizers say the event raised more than $1500 in online donations as of Saturday afternoon.
