I was guiding two friends down a route once that included a short 5 minute boot pack. They saw fresh snow below and decided to drop in instead. I followed them to save them. It was a night full of avalanches, rappels, ice climbs and running belays. I was so pissed off. At one point one of them said we should huddle together in a cave that we found and wait until morning. I snapped back, as long as we can move we will continue to do so. 19 hours from when we started we made it to town just as mountain rescue was about to go look for us. That was my biggest unplanned adventure. We were fortunate to make it out alive.
Sounds like these kids went down the Bucklin Trail.
