John poking at something troublesome

Welcome to class, BYU geology and Mr. Rad’s Bonneville 6th grade! Can you find the crevasse in this picture? Why isn’t it a gaping hole? Why do you think we tried not to walk on it anyway? How big is it, and which direction are the stresses oriented? Why and where do crevasses form in ice? Watch for some other pictures of the beautiful hexagonal ice crystals that form inside these crevasses. This is another reason not to fall in – these crystals form at very cold temperatures…

Much love from the Miller Range,
