How do mountain glaciers differ from piedmont glaciers?

Mountain glaciers are a broad category of perennial ice masses—excluding the Antarctic and Greenland ice sheets—that are typically confined to specific paths or channels within mountainous terrain. Because of the complex nature of mountain landscapes, these glaciers take various forms, such as valley glaciers, which flow through valleys, or cirque glaciers, which are short and wide and occupy mountain amphitheatres.12

In contrast, piedmont glaciers represent a specific development where glaciers spread out at the base of mountain ranges. They are formed by the convergence of the ends of valley glaciers as they emerge from the mountains onto flatter terrain. While mountain glaciers are generally restricted by the shape of the channels they occupy, piedmont glaciers are characterized by their expansion across the lowlands at the foot of the mountains.13
