Outer Edge Performance's herd of vertically inclined guides combines more than 50 years experience and multiple safety accreditations that ensure safe climbs at venues such as Boulder Canyon and Garden of the Gods. Student climbers slip on provided footwear, helmets, and harnesses before instructors spend four hours teaching small groups of five or fewer how to safely smear a slab and tame wild sediment. In addition to mastering rock faces, students build teamwork by ensuring peers' safety and double-checking their equipment. For an added challenge, ice climbers prepare to summit more slippery surfaces during the ice-climbing trip. Four hours of deft arctic instruction teach pupils to scale ice-covered terrain using specialized equipment including sharp ice axes, spiked crampons, and a pocket dictionary of yeti-speak.
