Matanuska Glacier is a valley glacier in the US state of Alaska. At 27 mi long by 4 mi 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 mi northeast of Anchorage in Glacier View. The glacier flows about 1 ft per day. Due to ablation of the lower glacier,, the location of the glacier terminus has changed little over the previous three decades.

Ownership and access

The glacier is located in Matanuska Glacier State Recreation Site, an Alaska State Park with trails and a small campground. Although the park is public, a private entity affiliated with Cook Inlet Region, Inc. charges a toll on the only bridge connecting the park to Alaska Route 1.

Name

The glacier is the eponym of the Alaska Marine Highway ferry MV Matanuska.
