Written Report:
Nice day touring up the SE ridge of Mt. Bailey. Clear skies and the air temp was approximately -10C in the morning with surface hoar present everywhere. Dug a 150cm pit at 7600ft on a 30 degree slope with a ENE aspect. 25cm of fluffy wind deposited snow sat atop a sandwich of knife-hard crusts spaced about 5cm apart. ECTN14 with only a small fracture 2cm above the uppermost crust (~20cm from the surface). Shovel shear after 30 taps revealed no propagation of this fracture-- instead resulting in a planar shear on the lower of the two crusts with a bit of force applied (approximately 30cm down). Descended the south bowl in variable snow conditions. No evidence of avalanche activity anywhere. Skinning out around 6000 ft elevation in the early evening and the surface hoar was reforming/growing-- some crystals were ~3cm long by 7pm. I hope this layer won't be a persistent problem with all of the snow that fell the next day!
