Why is the Malaspina Glacier considered a piedmont glacier?

The Malaspina Glacier is classified as a piedmont glacier because it consists of a large lobe of ice that has spread out over level terrain at the base of a mountain range.1

Specifically, it forms when the terminus of a large mountain-valley glacier exits a confined mountain path and expands onto the flat land below. As the world's largest example of this type, the Malaspina Glacier flows from the St. Elias Mountains and covers approximately 1,500 square miles along the southern base of Mount St. Elias in Alaska.12
