Which technique is essential for mountain terrain rescues with crevasses or avalanches?

• A. Use powered tools to break ice
• B. On-site medical imaging
• C. Boat-based lift rescue
• D. Rope systems, anchored belays, rescue knots

Answer: (D)

In mountain terrain rescues, especially around crevasses or in avalanche zones, creating a reliable system to protect both rescuers and the victim is essential. Rope systems with anchored belays and rescue knots provide the framework for controlled movement, safe lowering or hauling, and solid progress into and out of dangerous terrain. Anchors give a stable point to attach the rope, belays manage friction and prevent falls, and rescue knots tie the pieces together, enabling safe transfer between lines, patient handling, and secure operations on steep snow or near ice walls. This combination is what makes it possible to reach a victim, stabilize them, and extract them without adding risk to the rescuers. Other tools like powered ice tools, on-site medical imaging, or boat-based lifting aren’t the core means of performing these mountain rescues.
