Which technique is essential for mountain terrain rescues such as crevasse or avalanche scenarios?

• A. Use powered tools to break ice
• B. Rope systems and anchored belays
• C. Field surgery on-site
• D. Water-based flotation

Answer: (B)

Rope systems with anchored belays provide the safety framework that makes mountain rescues possible in crevasse and avalanche environments. Building solid anchors in snow, ice, or rock and threading a rope through them lets rescuers move people and gear without relying on unprotected footing. Belays control how tension and load are applied, so you can lower, halt, and haul a patient or rescuer smoothly, even when terrain shifts or loads are uncertain. The redundancy of multiple anchors and the ability to use pulleys and hauling systems means you can adapt to the space and conditions, maintain safety for everyone on the rope, and perform extraction without creating additional hazards.

Other options don’t fit the context. Using powered tools to break ice isn’t a standard, reliable rescue method in crevasse or avalanche scenarios and can jeopardize stability. Field surgery on-site is not a typical or safe approach for mountain rescues, where evacuation to medical facilities is usually required. Water-based flotation has no practical role in most mountain rescue settings.
