Matanuska Glacier is a valley glacier in the US state of Alaska. At 27 miles (43 km) long by 4 miles (6.4 km) wide, it is the largest glacier accessible by car in the United States. Its terminus feeds the Matanuska River. It lies near the Glenn Highway about 100 miles (160 km) northeast of Anchorage in Glacier View. The glacier flows about 1 foot (30 cm) per day. Due to ablation of the lower glacier, as of 2007, the location of the glacier terminus has changed little over the previous three decades. Nearby state park: An Alaska State Parks facility, the Matanuska Glacier State Recreation Site, is a 229-acre (93 ha) park with trails and a small campground. (Source: Wikipedia.org, CC BY-SA)
