Période

ca. 1971-1977

Canada

Taken from reference: 1 Used in a snow pit to conduct snow profile observations, to measure the depth of the various layers of snow. The hand-written inscriptions CAA (Canadian Avalanche Association) and BCIT/NRC (British Columbia Institute of Technology / National Research Council) speak of the Peter Schaerer era when the NRC ran avalanche training courses for industry in the 1970’s and 80’s. It was most likely used to conduct snow profile observations in education and training courses and programs.

Fonction

Used for measuring the depth of snow to assess snowpack stability in avalanche forecasting.

Technique

Taken from reference: 1 An example of a typical hardware store bought collapsible ruler, adapted for use in snow science folding ruler and used by avalanche professionals. Still used today (2013), this type of lightweight ruler is a standard used and found in snow science kits to conduct snow profile observations.
