I am still scratching my head after seeing the old snow surface still warm and wet. The rounded grains are large in size 4-5 mm and very wet. These loose wet grains were soft when pushing my hand into the snowpit wall (fist hardness) and one could only imagine them propagating - especially with 40 cm of new snow on top. However, after two extended column tests with no propagation I moved onto a shovel tilt test and still had no shear or any layering that caused me concern. The new snow was mainly made up of broken particles and heavily rimed grains and maybe a touch of graupel in the mix.
From what I observed the new snow was bonding very well to the old snow surface and there was little to no instabilities within the storm snow. We did ride terrain steeper than 35° degrees in steepness and noted no cracking or sluffing or any new snow instabilities.
