I never noticed this before but the shadows on a december early morning are very deceptive. Shadows normally fall east or west during the summer, spring and fall. Y’know cuz the sun moves across the sky east to west. So explorers can tell which direction they are going. But the december shadows in the morning actually fall north-way, because the sun is so low in the sky. It makes me wonder if hikers have ever gotten confused and thought that the december morning shadows are falling west-ward instead of north-ward.
