Abstract
The glaciological studies were carried out on the ground ice in the USA CREEL Permafrost Tunnel, Fairbanks, Alaska, as a part of the JAPANESE ARCTIC HYDROSPHERE EXPEDITION 1968. After classification of ground ice as Ice wedge, Pond ice, Clear ice, Vein ice, the results of ice layers were described in relation to the stratigraphy of the section inside the tunnel. It was found from the fabric analysis of ice on the basis of observation by polarized light that the stereogram of the crystallographic orientation of grain of Ice wedge showed simillar characteristics to those of glacier ice.
