Synopsis of the slide
Will Grenier, his younger sister Cassie and their friend Erin Gibbs were scrambling up a talus slope on their way to summit the Middle Teton in August 2017 when a boulder slide cut loose above Cassie.
At the time, 24-year-old Cassie worked as a recreational therapist and her job involved taking kids with troubled backgrounds into the great outdoors. Going up the Middle Teton was supposed to be a day off for her. But what the trio expected to be a typical day hiking in the park turned into a fight for survival.
“So I see her running. I see a dust cloud. I see rocks going down the mountain, and I see them all kind of coming together,” Will recalled. “The rocks start kind of flying over her head, and [I] had absolutely no idea where Cassie was.”
• Carry more than one first-aid kit. If the person wearing the first-aid kit becomes trapped, the kit can be inaccessible.
• As snow melts away from snowfields, rocky talus slopes next to the snow can become especially unstable. Traveling on a snowfield can be safer if you have an ice ax and know how to use it.
• Pause the adventure and speak up if you are feeling uncomfortable about the route.
• If you can, remain calm like Cassie Grenier.
