4.1.4 Day 1, 2PM: Aspect

Aspect is the direction that an object or tilted ground surface faces. We're looking at a large tree stump covered in snow. Notice the dramatic melting on the south-facing side and the undisturbed snowpack on the north-facing side. The snow on the dark, cold side remains as it was when it fell, whereas a melted layer has formed (and subsequently crusted) on the south-facing side.
