Which test uses a ski pole to quickly understand the layers in the snowpack?

• A. Hand shear test
• B. ECTN## (No prop fracture)
• C. Ski pole test
• D. Tilt test

Answer: (C)

Understanding snowpack layering quickly is essential for on-slope safety. The ski pole test is designed for rapid feedback: you probe the snow with a ski pole and pay attention to how each layer feels and sounds as you move the pole through it. Changes in resistance, a hollow or muffled sound, or a noticeable drop in support as you pass from one layer to another point to boundaries between layers, which can indicate a weak interface that might fail under stress. This quick, tactile method gives you immediate insight into the structure of the snowpack without digging a full snowpit or performing longer procedures.

In contrast, hand shear tests, extended column tests, and tilt tests require more setup, time, or specific conditions, and they provide more detailed or widespread assessments rather than the fast, on-the-spot sense of layering that the ski pole test offers.
