With her purple ponytail dangling beneath a grey helmet, Ceri Evans kicked one crampon-clad foot, then the other, into the plywood walls of The Ice Coop, a unique Boulder climbing gym, on a recent snowy Wednesday evening. Smoothly and purposefully, 15-year-old Evans began placing the sharp metal tips of her bright orange ice climbing tools onto holds attached to the wall, periodically biting the handle of one tool as she readjusted her grasp. Suspended by her spiky boot toes and the picks of her tools, she moved horizontally along the wall, confidently kicking her feet and moving to new holds. If you go The Ice Coop, 2500 47th St., Unit 2, Boulder; 720-219-0977.
