A white curtain of Ptarmigan Falls pours over a sheer lip, the cascades framed by pale granite along the Grinnell Glacier Trail. Morning light makes the water sparkle as it drops into a hanging valley carved by ice over millennia. This is a glacial waterfall—the direct result of Pleistocene glaciation and differential erosion.
