SDC
- Label:
- Definition: (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.
