Parks Canada operates a snow study plot in Rogers Pass National Historic Site of Canada in Glacier National Park, B.C. Combined with meteorological data, the daily information gathered, recorded and monitored from studying the snowpack was used to produce daily avalanche forecasts and bulletins. Set in the context of “Snow Research” for “Avalanche Control”. - Function
-
Part of the snow study kit, these standard thermometers were used to measure the temperature within the snow pack, where temperatures can fluctuate drastically (called the temperature gradient) - from the warmer snow temps which promote high crystal growth rate found in deeper layers, to cooler temps that favor slower crystal growth rate typically found nearer the surface. - Technical
-
The standard thermometer can be used to determine air temperature as well as snow temperatures within the snowpack. - Area Notes
