Ice Climbing is the activity of climbing ice formations. These formations come in all forms including: icefalls, frozen waterfalls, rock slabs covered in ice, and cliff sides frozen with water. These formations can be man made and/or nature made. There are two types of ice climbing: Water Ice Climbing & Alpine Ice Climbing. Water Ice is usually found on cliff sides from liquid water flows and Alpine ice is generally found in the mountains and is frozen precipitation. Ice comes in all formations from soft to hard and the climbing grades differ from that of rock climbing. Mixed climbing is the combination of climbing both rock and ice.
