Which slope orientation typically has no direct sun exposure in winter?

The orientation of a slope plays a crucial role in its exposure to sunlight, especially during winter months when the sun is lower in the sky. A north-facing slope receives minimal direct sunlight compared to slopes oriented toward the east, south, or west. This is primarily due to the angle of the sun's rays; during winter, the sun tracks lower in the southern part of the sky, making it difficult for north-facing slopes to receive direct sunlight.

In contrast, east-facing slopes catch the morning sunlight, while south-facing slopes benefit from the sun throughout much of the day. West-facing slopes can receive sunlight during the latter part of the day. As a result, north-facing slopes are typically colder and can remain shaded longer, which affects factors like snow retention and vegetation growth.
