Snowpack Summary
A very light skiff of snow may have buried a surface hoar layer that lies on top of old surfaces comprising crusts and old wind slab. However, with only a centimetre or so of new snow, it's not certain that surface hoar crystals of 5 mm or more would get properly buried. Successive melt-freeze cycles have produced crusts on all aspects at lower elevations as well as on south-facing slopes higher up. The old wind slabs are no longer causing concern in most areas. A facet layer, which formed around 20th January, is buried around 60 cm and is reported to be gaining strength. It showed hard, resistant planar results in a compression test at treeline in the Hankin area on Sunday.
