Fact or fiction mountain areas of the southwest could be cold or snowy?

Fact. Mountain areas in the southwestern United States, such as the San Juan Mountains in Colorado or the Sierra Nevada in California, can experience cold temperatures and snowfall, especially during the winter months. Elevation plays a significant role in this climate variability, leading to colder conditions and significant snowfall in higher elevations compared to the surrounding lowland areas. These mountains are popular for winter sports and are known for their picturesque snowy landscapes.
