Rainier gives birth to a river
Look in the lower right of this pic, between the trees, and you can see the snout of the glacier. At the bottom center is the terminal moraine, made up of silt and rocks transported down the mountain by the glacier in colder times, when it filled its valley much more than it does today.
Blow up the pic and you can see waterfalls coming off the mountain above the moraine. Rainier is shedding much of its moisture as ice and snow melts. But in about eight weeks, the trend will reverse, and for the following seven months or so, the mountain will accumulate much more snow than it sheds.
About ten miles downstream, the Nisqually River runs strongly, but fills only a small fraction of its channel. During floods the river assumes massive proportions, most recently in 2006 when a Pineapple Express storm raised the snow level far up on the peak and produced devastating flooding that trashed much of the National Park. Notice the trees in the center of the rocks...grim survivors, barely, of the floods. Now, in quieter times, the river flows with the silty runoff from the glaciers and snowfields on the slopes of Mt Rainier.
