Last week I taught a Alpinism 1 course for American Alpine Institute. It was a great trip with good weather almost every day except the summit day. In this course we start out teaching the skills needed to climb the mountain, and then on the final day we make an attempt at the summit.
A two person rope team crevasse fall is a serious thing. Here we allowed each person to catch a fall and fall in a real crevasse. The two extra ropes in the photo are back up lines in case the fall is not stopped.
Our headlamps lighting up the fog on our summit attempt. As you can see the weather was not cooperating, and very strong winds were causing a huge lenticular cloud to cover the summit. Due to the strong winds and low visibility we turned the group around at about 9,000ft.
