Manual snow survey sampling from snow courses consisting of 10 measurement points. Measurements of snow water equivalent (SWE), and snow density are expressed as an average across the snow course. Measurements are taken three times a year at the start of March, April , and May.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows the snow cover data, referring primarily to the presence and total depth of a snow cover on the surface of the earth, across Canada. This is in contrast to data characteristics of snow cover depth, which increases by the occurrence of freshly fallen snow, but decreases by melting, wind action and settling. Two maps of these maps show the mean dates of the occurrence of first and last snow covers by one inch (2.54 cm) or greater. These are not necessarily the average dates to the beginning and ending of a continuous snow cover, since the snow cover may form and later disappear once or several times during a winter season.

Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate that shows two maps for the annual total precipitation. Annual precipitation is defined as the sum of rainfall and the assumed water equivalent of snowfall for a given year. A specific gravity of 0.1 for freshly fallen snow is used, which means that ten inches (25.4 cm) of freshly fallen snow is assumed to be equal to one inch (2.54 cm) of rain. The mean annual total precipitation and snowfall maps on this plate are primarily based on thirty-year data during the period 1921 to 1950 inclusive.

This measure is based on snow-tracking data from established snow-transects. Trends for this metric focus on wary carnivores (cougar, lynx, wolf, and wolverine) on transects within 5 km of the Townsite. Data collected include location, species presence, number of animals, hours since snow, & snow-depth.

This map shows the median date of snow-cover onset (defined as the first date with 14 consecutive days of snow cover greater than 2 centimetres in depth) computed over 18 winter seasons (1979 to 1997). In areas with permanent or semipermanent snow cover (for example, Arctic ice caps) or in areas with irregular or ephemeral snow cover (coastal British Columbia), researchers were unable to compute the median values. The main feature of the map is the rapid southward extension of snow cover over Canada during the September to December period. The moderating influence of Hudson Bay can be seen over northern Quebec, where snow cover starts later than in the equivalent latitudes west of Hudson Bay.

The measure is based on snow-tracking data from 3 established snow-transects in the Kicking Horse Valley. Trends for this metric focus on wary carnivores (cougar, lynx, wolf, and wolverine) though prey (ungulate) data will also be collected. Data collected include location, species presence, number, days since snow, & snow-depth.

This map shows the median date of snow-cover loss (defined as the last date with 14 consecutive days of snow cover greater than 2 centimetres in depth) computed over 18 winter seasons (1979 to 1997). In areas with permanent or semipermanent snow cover (for example, Arctic ice caps) or in areas with irregular or ephemeral snow cover (coastal British Columbia), researchers were unable to compute the median values. The end date contours follow topography more closely than start date due to the influence of elevation on total snow accumulation and air temperature. The date of snow-cover loss has important implications for wildlife (for example, bird migration and nesting), vegetation, local climate and hydrology.
