High Stemming
Technical climbing in high-consequence slots
High Stemming in Trail Canyon
High Stemming is where you climb above the canyon floor using your back, feet, and hands to span the slot and maintain forward progression.
This occurs when the canyon floor is too narrow to squeeze through, requiring you to climb up and over the constriction. At this point, canyoneering shifts from a casual romp to a **serious endeavor with life-or-death consequences.**
Critical Warning
In high-stemming canyons, there is generally no way to protect the less experienced. Every member of your group MUST be capable of completing the climbing challenges involved. A slip or fall will result in serious injury or death. These are not suitable for weekend warriors.
The Dreaded Silo
If chimneying 40+ feet above the floor doesn't get your blood pumping, many stemming canyons feature the "Silo." This occurs where the canyon widens significantly, requiring either a massive reach to chimney across or a strenuous climb down and back up. These are some of the most physical and dangerous positions found in the desert.
Extreme Examples
DDI (Escalante): Crumbly walls and narrow floors. Requires hours of chimneying 30+ feet up on "desert choss."
Sandthrax: Requires 5.10 off-width climbing skills just to get above the constrictions. Groups have been stranded here without the necessary climbing gear.
