the snow for about 15 feet on all sides of the hut caused the Ice to 

 spring back into place and resume its former level; the water level 

 in the icehole dropped accordingly. Snow removal was resorted to on 

 three occasions. A large Navy D-8 tractor with 16 -foot blade would 

 do the job in less than a day. Finally, the hut rested in what 

 appeared to be a shallow depression with high banks of snow surround- 

 ing it at a distance of 100 feet on all sides.
