If you dare, dip your feet into the icy water of St. Mary Lake. The glacier-fed water adds a new twist to the term “refreshing.” It’s one of many sensory experiences at a park that attracts more and more people who want to see the glaciers before they are gone. 

Glacier National Park, in northern Montana, is a crown jewel of the United States. Its pristine landscapes draw millions of visitors a year, to see its majestic mountains, jewel-colored waterfalls, carpets of wildflowers, and wildlife ranging from bald eagles to mountain goats and bighorn sheep to grizzly bears. But mostly people come to see the glaciers, these fields of ice that – by definition – move under their own weight, picking up rocks and debris that sometimes stain their brilliant blue hue with a hint of grey.
