Observations

- Went for a full day of trail breaking and skiing over on earthquake dome. Was a good simple terrain choice for today to assess new snow load on PWL as well as the struggles with access / parking.

- Notable observations from today : Wind slab was mostly un-reactive on the top of earthquake dome, besides some very small shooting cracks. New snow seemed to be mostly unconsolidated and only failed when undercutting test slopes.

- We did have some isolated whumping and collapses on E - SE aspects on the approach to EQ dome.

- Snowpit data: NE aspect 8600ft - HST 60cm //// CTM (SC) down 60cm //// ECTN21 down 60cm on near surface facets
