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) north-east of Anchorage. Matanuska 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 changed little over the previous three decades.
Alaska is the largest state in the United States by area. It is situated in the northwest extremity of the North American continent, with Canada to the east, the Arctic Ocean to the north, and the Pacific Ocean to the west and south, with Russia further west across the Bering Strait. Approximately half of Alaska's 710,231 residents (as per the 2010 United States Census) live within the Anchorage metropolitan area. Alaska is the least densely populated state of the U.S.Source: http://en.wikipedia.org/wiki/Alaska
