Multiple methods are used to safely travel over ice. If the terrain is steep but not vertical, then protection in the form of ice screws can be placed in the ice and attached to the rope by the lead climber. Each climber on the team must clip past the anchor, and the last climber picks up the anchor itself. Occasionally, slinged icicles or bollards are also used. This allows for safety should the entire team be taken off their feet. This technique is known as Simul-climbing and is sometimes also used on steep snow and easy rock.
If the terrain becomes too steep, standard ice climbing techniques are used in which each climber is belayed, moving one at a time.
