Abstract

Observations have been carried out on needle ice striped ground in southwestern British Columbia and in New Zealand. The stripe orientations are shown to develop parallel to the shadows cast by the sun when the needle ice, with its soil cap, thaws and collapses. Differential thaw of the needle ice, and adhesion of some unsupported particles of the soil cap to the adjacent needle ice supported soil cap, are believed to contribute to the striping of the ground.
