The Matanuska Glacier is a frozen 27-mile long river of ancient ice. Thousands of years old, this massive glacier is tucked up into the head of the Matanuska Valley, located about 45 miles north of Anchorage. On this Alaska outdoor experience from Salmon Berry Tours, you will spend over 2 hours directly on the glacier with a glacier guide. You’ll learn how the Matanuska Glacier was born and how it shaped the landscape in the Matanuska-Susitna Valley while exploring blue meltwater pools, ice formations and deep crevasses.
