Task: Question Answering
Input (English): Context: With one big gust whilst riding 60 mph you may not have any choice whether you were going to end up in the gravel or not . All told though I made it through without any falls . After the 3rd night camping I got to El Calafate and went to see the Glacier there . Well all I can say is that this Glacier was seriously impressive and well worth the entrance fee . 
Question: What is the reason that paying a fee to see a glacier would be worth it ?
Output (English): It is an impressive natural feature and with global warming these sorts of sights may be historical .
