The intense, snowy winters of Logan Pass are iconic. Deep snowpack that lasts well into summer has both aesthetic and ecological value in Glacier.    

The literal uphill battle of plowing snow off Going-to-the-Sun Road is a much-watched harbinger of spring here. In recent years, however, the struggle is not to resist winter, but to preserve it.   

Rising temperatures from a warming climate have meant falling snowpack. Over the past 80 years, western Montana and the Pacific Northwest have seen drastic declines in snowpack volume.   

Lower elevations especially have seen a decrease in snowpack since the 1950s. This trend is expected to continue unless climate change is swiftly addressed.
