The Rocky Mountains experience the most snowfall during the winter due to their high elevation and climatic conditions.

The Rocky Mountains receive the most snowfall during the winter months due to their high elevation and geographic location. As moist air from the Pacific Ocean moves eastward, it is forced upward by the mountains, cooling and condensing into snow, especially at higher elevations. This process, known as orographic lift, results in significant snowfall in areas like Colorado, Wyoming, and Montana. The combination of winter storms and mountainous terrain creates ideal conditions for heavy snow accumulation. Other regions, such as the Great Plains, Pacific Northwest coast, and Southeast coast, receive much less snow due to different climatic factors.
