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.

[2] It lies near the Glenn Highway about 100 miles (160 km) northeast of Anchorage in Glacier View.

[3] The glacier is located in Matanuska Glacier State Recreation Site, an Alaska State Park with trails and a small campground.

[4] 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.

[5][6] The glacier is the eponym of the Alaska Marine Highway ferry MV Matanuska.
