Print article An Anchorage man died Friday when the snowcat he was driving broke through lake ice in the Matanuska-Susitna Borough, the Alaska State Troopers said. Scott Gagne, 57, was driving the snowcat around 4:30 p.m. on Hewitt Lake near Skwentna when the large tracked vehicle fell through the ice, troopers wrote in an online report. Austin McDaniel, a spokesman for the troopers, described the snowcat as a “a larger tracked vehicle with a front plow that was transporting a snowmachine.” Snowcats are often used to groom ski trails, but McDaniel said it was not clear if Gagne was grooming a trail when the machine broke through the ice.
