Ice climbing involves the climbing of icefalls, frozen waterfalls, cliffs and rock slabs covered with ice refrozen from flows of water. It’s broadly divided into mountain, alpine ice and water ice. The sport itself evolved out of rock climbing at high altitudes where rock climbers had to learn how to navigate icy and slippery areas as they worked their way up a mountain or rock wall. This in turn led to climbers becoming specialized in the sport and developing tools/ gear specifically for those areas. Over time, it has evolved into a sport all unto itself.
