1. Carefully observe the layers of your wall. How many layers can you see? How are the layers different? Alike? Record your observations.
2. Slowly slice the wall of your trench from top to bottom with your meterstick, paying close attention to changes in resistance.
- Did the snow feel the same all the way down? - Was it harder or easier to slice at any particular place? - Did you meet any resistance that could indicate an ice layer?
3. Insert stakes horizontally at the top of each layer.
4. Measure the height of the top of each layer from the ground surface up. This may work best with two people; one person holds a measuring stick while the other reads and records the measurement.
5. Record an “H” on the profile drawing for any layer that felt hard.
