here is an article I wrote on it from 2 years ago: Jackson Hole Steep and Deep Snowboard Camp | Snowboarding News and Updates | SNOWREV
I only had one hike/run with the camp that year. I mostly wrote from the 8+ years of experience at JHMR. The camps are run well by top notch staff who can assess your abilities and cater to advancing you to the best of your abilities. It doesn't matter how in shape or prepared you think you are. The elevation and mountain will kick your ass. I've seen many Pros get schooled by the natural forces there. So the goal for the coaches is to take you as far as you can go but while keeping you close from leaving your comfort zone.
You will learn, be in awe, and most defiantly score some righteous pow. Their knowledge and route finding are what you pay for. These guides can "take you there" to that place dreams are made of.
