QUESTION 9

1. GigaPan 5.) General question – Does the glacier in this photo appear to be advancing or retreating?GigaPan 5.) General question

   		Advancing: you can see it plowing up everything in its path
   		Advancing: it’s flowing downhill
   		Retreating: the valley it sits in shows many features that indicate the glacier used to be larger and extend further downhill from its present position.
   		Retreating: the valley downhill is V-shaped and shows no sign of more extensive glaciation.
