Dyeing of Snow Surfaces to Observe Structure

A surface coloring method is described for highlighting the natural stratigraphy and load-induced structure in snow at low ambient temperatures in confined areas. The method includes planing the wall of a snow pit and then dyeing the surface using an alcohol dye applied by an electric sprayer. Surfa...

Description
Summary:A surface coloring method is described for highlighting the natural stratigraphy and load-induced structure in snow at low ambient temperatures in confined areas. The method includes planing the wall of a snow pit and then dyeing the surface using an alcohol dye applied by an electric sprayer. Surface heating and backlighting are also discussed as methods for revealing hidden detail, especially when photographic evidence of the snow structure is important.
