North-facing slopes receive very little heat from the sun in midwinter. Conversely, south-facing slopes receive much more heat. Therefore, a north-facing slope will usually develop a dramatically different snowpack than a south-facing slope. • East-facing slopes catch sun only in the morning when temperatures are colder; west-facing slopes catch the sun in the warm afternoon. Consequently, east-facing slopes are colder than west-facing slopes (Figure 3-16).
