Matanuska Glacier, just 100 miles north-east of Anchorage, Alaska, is the largest glacier in the United States that you can access by car. This valley glacier is located in southcentral Alaska’s Matanuska-Susitna Valley (known to the locals as Mat-Su or The Valley) and terminates in the Matanuska River.
The Mat-Su was carved by glaciers, leaving thousands of lakes in their path. About 10,000 years ago, the Matanuska Glacier retreated and remains as a reminder of those great, gone landscape sculptors. At 27 miles long and 4 miles wide, it’s a swath of moving ice that is one of the most easily explored in North America.
