The heaviest snowfalls typically occur during the months of December and January, when storms from the Pacific Ocean bring moisture to the park. These storms can produce several feet of snow in a single day, and they can often close roads and trails. The snowpack typically reaches its peak in late February or early March and then begins to melt as the weather warms up in the spring and summer.
Glacier National Park is a popular destination for winter recreation, including skiing, snowboarding, snowshoeing, and ice skating. The park's rugged terrain and abundant snow make it a challenging and rewarding place to experience winter sports.
