Hanging valleys often end in waterfalls above a deeper main valley
A trunk glacier cuts its valley deeper and faster than smaller side glaciers. When the ice melts, the tributary floors hang high on the main wall — hanging valleys that spill rivers as waterfalls.
Yosemite-style cascades and many alpine falls sit at these mismatched junctions. The drop records unequal ice power, not just scenic rock.
Waterfalls can be glacier math. Hanging valleys link mountain carving to waterfall drama where side streams leap into the deepened trough.
