We skied 2 laps off oboe shoulder and observed multiple sz 1 storm and soft wind slabs release on NW aspects. We observed rapid loading on lee slopes throughout the day.

- 1 (Sz1) skier accidental triggered by another party near ridge line. The slope was not steep enough for the slab to travel more than a few meters and no one was caught or carried.

- 2 (Sz1 - 1.5) suspected natural releases at ridge line. Another party was unsure if one was natural or remotely triggered by them from below.

We did not observe any avalanche activity on other aspects.

We were surprised to find slabs breaking easily in the storm snow on slopes right around 30°.
