Quick Summary

A trunk glacier is a valley glacier formed when multiple tributary glaciers flow together. Glaciers are large masses of perennial ice that form on land from recrystallized snow and show evidence of flow. When confined by valley walls, glaciers deepen and widen the valley floor, transforming the typical V-shaped stream valley into a U-shaped glacial valley. This U-shape offers the least resistance to the moving ice. Smaller tributary glaciers erode their valleys less deeply than the main glacier. When the ice melts, these less-eroded valleys are left high on the walls of the main glacial valley, forming hanging valleys.123
