Variable rain crusts on Flagpole

We started at 09:30 this morning @ 6600'. Skies were clear, no winds, with temps well below freezing around 20F. Snow on the way up consisted of a variety of rain crusts all the way to the saddle. Below 7300' the rain crust was strong and supportable. There was widespread surface hoar from 3-5mm on the surface within these elevations. Above 7300' the rain crust became a little more breakable with soft snow below it which felt like a near surface facet layer beginning to form. Above 7800' the rain crust became a little weaker mixed with new snow particles on the surface from yesterday's storm. Also above 7800', under the crust was a clear layer of graupel preserved directly below it. Continuing up from there the surface snow became more wind affected and back to a supportable surface the last few hundred feet. My second pit profile was on a protected steep 38 degree slope and had some CT results scoring CT21 Q1 above a crust layer@ 7cm down and a CT 28 Q2 on the Dec.11th layer and ECTX during the extended column test. Ski conditions at the top were pleasant as the rain crust was weak and breakable and snow was soft below it. However, we did have to pump the brakes and make the exchange back to the very supportable crust in the lower elevations where rain was probably more abundant. The crust in lower elevations never really softened until back in the flats near 6600' at the end of the day and in the sun.
