Comment on “Grain boundary ridge on sintered bonds between ice crystals” [J. Appl. Phys. 90 , 5782 (2001)]
Ridges have been observed at the bonds between sintering snow grains. Images collected using the scanning electron microscope (SEM) and x-ray analysis of Antarctic snow are presented. These indicate the ridges are composed from soluble impurity and not ice or water as previously suggested. The ridge...
