Winters in Glacier National Park are known for their massive accumulations of snow. The average snowfall in the high country is over 10 feet and snow depth at the "Big Drift" during spring plowing of the Going-to-the-Sun Road often exceeds 60 feet!. Spring weather usually determines whether or not hydrologic activity will be in the headlines. In 1964 a heavy winter snowpack combined with warm spring rains to produce catastrophic flooding over large areas of the Park as well as portions of the Flathead Valley. Floods have also damaged the Polebridge area (on the North Fork) in recent years and flooding periodically occurs in the St. Mary River system, especially along Divide Creek near the village of St. Mary.

Grizzly bears in the park have a wide variety of food sources, including glacier lily bulbs, insects, and berries. They may also make an early season meal of mountain goats that were swept down in avalanches over the winter.
