When passageway modification becomes necessary there are two principal considerations. The safety of the patient, and the overall stability of the passage. Modification must not compromise either of these. For this reason, the "blasting" technique employed is not something that would make interesting television or movie scenes. We focus on minimal pressures designed to crack rock, and not displace it. We can then use wedges to propagate the crack, and partition the rock. In some cases we can forego any blasting, and use the wedges, alone, to crack the rock.

Each year team members are required to recertify their Rope Rescue Operator and Support skills. These involve ascending a rope past a knot and reblay, changing over (while hanging), and descending the same rope. We also perform a single rope "pick-off" of a stranded climber, and show proficiency in a number of knots. For Rope Rescue Operator, we need to construct various anchor systems, mechanical advantage systems, and a litter tie-in.
