See above, and ECTN 26 down 42 validate the overall cohesiveness of the slab, yet several PST scores of 26 and 27/100 at the same layer: 42 down on 2 mm facet support the fact that potential instabilities are out there where this dense slab overrides these buried PWL's.
OF CONCERN: Is the possibility of folks trusting ECTN scores as indicators of stability, and hense may allow them to trust the "bridging" of the slab as a reason to ride steep slopes. ECT tests are not valid in snowpacks with a dense slab that won't allow for the loading steps to induce reactivity to the buried weak layers.
Also of concern is the lingering presence the December mid storm facet layer that can be found around 28 cm down. Test scores of CTM continue to yield SP and SC shears on .5 mm facets, and if this layer continues to be a player it may be likely to be the initial failure point when we get the next load. Once this layer initiates, the potential for step downs to the previously cited mid pack advanced facet layers will be likely.
