| SDC - (snow density competency) - a qualitative description of how
readable the sample was extracted from the snow pit. One (1) indicates that a
good sample, with little snow loss was collected, 2 indicates some loss of snow,
while 3 indicates that obtaining a nearly complete sample was not possible due to
either the lack of cohesion of the snow or the snow wasto hard to collect a sample. |
