While out in the advisory area yesterday, my touring partner and I were unable to get any of the recent storm layers to propagate in any of our Extended Column Tests. This does not mean that these slabs aren't going to cause any problems today or in the future. Currently these slabs ARE reactive (initiation) at the interface between the different layers from the past storms (CT 13 40cm from surface Q2), but lack the cohesion that they need to propagate (ECTX). The rain crust from mid-November is still holding strong at 5 cm thick and is buried approx. 110 cm down in the pack at 7500 feet.
