Extract

The scientific work to account for the sliding properties of snow and ice is not abundant. Osborne Reynolds suggested that a skate slid on ice owing to the lubrication caused by pressure-melting. Bowden and Hughes, after studying the measurements made by the last-named as physicist to our glaciological expedition to the Jungfraujoch in 1938, formed the opinion that this could not alone account for the action of ski sliding upon snow. I had reached a somewhat similar conclusion some years ago after a study of the structure of snow crystals on the surface of snow fields.

The difference was so great that it was at least half as hard again to draw the sledge on the nickel runners as on the tarred maple runners.”
