A while ago a young lady visited the glacier with her wedding party the day before her wedding. This young lady has been there several times before. This day she stepped in a small stream but as the guy behind her said "one second she was there the next she was gone. I looked down and only saw hair floating I yelled then grabbed her hair. The guy in front of her helped me to pull her to safety". That young lady was my daughter. Should guides be required yes. $100.00 per person way to expensive. $100.00 per group would be fair.
