Our group toured up Alpental to near top of Lower International.
Observed whumpfing, isolated collapsing, and isolated cracks while skinning from 3,500’ to 4,000’.
Chose to dig a profile on ESE 40 degree slope at 4,000’.
- 63 cm snow depth
- top 2cm: pencil probe
- 2-16cm: 1 finger probe
- 16-19cm: 3cm rain crust
- 19cm-base: 1 finger probe
Column test failed during isolation above the rain crust at 16 cm depth. Fracture character undetermined.
We isolated a second column which failed both above and below the same rain crust with light tap to the back of the column.
