If you want to feel small, hike up the rivers that source at the base of one of Mt. Rainier's many glaciers. Carbon, Emmons, Nisqually, etc... This one happens to be the drainage for the Cowlitz glacier - ie the Cowlitz River. Perspective is hard without a good reference, but that's a fair sized river, not a creek. The glaciers have receded leaving these huge, rocky, scars, now downhill from the diminished glacier's lower tips that now drain melt & rain that summer brings.
