We just spent an incredible day exploring the underworld of Crazy Horse Buttress with the fabulous International Student Volunteers tour leader team.  Josh, Taw, Muad and Kreang guided Kieran, Pim, Queen and Mae into the exciting Anxiety State Crisis Cave.  It was the first of many potential cave explorations with the ISV group and we look forward to teaching geology and caving techniques to ISV students as they embark on their summer travel.  The ISV team was fantastic and they were full of energy and excitement.  Pim had never been caving or climbing before and was a true champion inside the exposed cave.  Thank you to the ISV team…you are all incredible!
