Weather Patterns in Glacier National Park

The western portion of the park, including areas around Lake McDonald and the Many Glacier Valley, receives more rainfall than the eastern side. The higher elevations of the park, such as Logan Pass, also experience more precipitation, particularly in the form of snow.
