In bad ice, how should ice screws be angled?

In bad ice conditions, the optimal angle for ice screws is to place them away from the anticipated load. This approach allows for a more effective transfer of forces through the ice and helps to prevent the screw from pulling out under stress. By angling the screw away from where the load will be applied, you create a more secure and stable anchoring point. This positioning helps to maximize the surface area and grip of the ice screw, enhancing its holding power in potentially compromised ice structures. In contrast, placing the screws towards the load or at inappropriate angles may increase the risk of failure, as the load could cause shear forces that might dislodge the screw more easily.
