Route & General Observations

Quick afternoon tour to check on snow conditions in the Ship Creek Area.
We were surprised by the 8″+ of new powder on top, and disappointed by the ECT results.
The snow pack is very weak, and has a propagating weak layer under a slab.
We kept our slope angles below 30deg after our pit results

Observer Comments

We had several small whumphs while traversing in thin snow (45-65cm) on West through South aspects at elevation 2200-2400ft.
We did NOT have whumphing while climbing the slope that we dug on, which was surprising given the pit results.
We saw the avalanche reported on North Bowl right after it happened. Poor visibility made it hard to tell many details or get a photo.
