What hazards were described at ABC?

• A. Ankle-breaking rocks and life-ending crevasses
• B. Smooth ice and gentle slopes
• C. Dense forest and wildlife
• D. Gentle breeze and clear skies

Answer: (A)

Hazard recognition in rugged terrain. Ankle-breaking rocks point to unstable footing and the risk of severe ankle injuries from loose or jagged ground. Life-ending crevasses reveal deep, hidden gaps in ice that can swallow a person if not detected, especially when the surface is deceptive. Together, these describe immediate and serious dangers that demand careful footing, tested routes, and safety measures like roped travel and proper spacing.

The other options describe conditions that aren’t as dangerous in this context: smooth ice and gentle slopes imply safer travel; dense forest and wildlife can present challenges, but they aren’t the dramatic, life-threatening features implied by crevasses and unstable rocks; and a gentle breeze with clear skies is favorable weather, not a hazard.
