So? Same difference. If the ground slopes non-perpendicular to the central 
light, object perpendicular to the ground will cast shadows. If a mountain 
is not perpendicular to the central light (remember that these mountains 
were not shaped by rain and geology) it could constantly overshadow an 
adjacent valley.
