Warming temps with noticeable sun coming through by late morning. Rain began with snow line at around 4,500ft or so by 11:30.

Lichtenberg SE slopes
|D2||WL-Wet Loose||O-Old Snow||N-Natural||Report|
Triggered rollerballs by mid-morning, then by 11 we were able to easily trigger wet loose slides on E and SE aspects below 5,200ft. Observed a couple large recent natural WL slides off larger slopes on Lichtenberg by noon. See avy occurrence entries.
We mainly wanted to observe how the recent snow and faceted layers above the early March crust were doing. The warm temperatures of the past few days have caused the 3/8 faceted layer to become moist up around 5,300ft, though the layer is still very weak (F), and the snow above is dense and moist (4F+).
Tilt tests were good in showing the poor bond of the early March crust with weaker facets and shallow slab above- blocks would slide off easily with minimal resistance. CT's and ECT's showed resistant planar and no propagation on NW aspect at 5.2k.
No cracking where we traveled, but I suspected above 5,500ft or so that layer has remained dry, and slab avalanches may have been easy to trigger today.
