Observations
Profile at 4840ft, NW revealed Jan 11th interface ↓35cm is of most concern. Clean shears in tilt test along with progressive compression with Compression Test (CTM11(PC)). Wet snow in the top 3cm w underlying new snow (DF, PP). No obvious wetting front, but I found moist snow in top 20cm as well as below the Jan 11th interface.
