Describe hanging valleys and explain how they form


Hanging valleys are glacial valleys connected to larger, deeper glacial valleys, with a significant difference in elevation between the two valley floors. Hanging valleys form where tributary glaciers flowed into larger trunk glaciers. The difference in elevation between the tributary and trunk valley floors is not apparent when the ice is present, but once the ice is gone floors of tributary troughs can be seen perched along the walls of the trunk glacial valley.
