Saint Mary's Glacier actually isn't a glacier at all; it's simply a snowfield that doesn't completely melt in the warmer months. The persistence of snow throughout the year caused people to start referring to the snow mass as a glacier, but it isn't actually moving down the valley (which is the distinguishing feature of a glacier). This is still a cool feature to come check out any time of year.
