rush — that is, as a strong wind — no fog is produced, as the vapor is 



distributed by the accompanying turbulence through too large a volume 



to produce saturation. (Fig. 106.) 

 GIANT FLOE: (I.A.2.e.)— A floe ranging in size from 3,000 feet to 



about 5 miles across. See floe. (Figs. 18, 19, 22, 35.) 

 GLACIAL: (II.B.) — Of or pertaining to a glacier. 

 GLACIATED: (II.B.) — Having been subjected to the action of glaciers. 



See glacier. 

 GLACIATION: (II.B.) — The alteration of any part of the earth's surface 



(usually by means of erosion or deposition) in consequence of glacier 



ice passing over it. See glacier. 

 GLACIER: (II. A.) — A flow of land ice from an area of ice accumulation. 



Glaciers originate in upland areas and usually terminate at sea level at 



high latitudes. A glacier, in contradistinction to an avalanche, moves 



slowly and is semi-permanent. Its extent is greater than that of an 



avalanche and it is composed of ice rather than snow. See land ice. 



(Figs. 69, 70, 86.) 

 GLACIER COVERED: (II.B.)— Describes areas now covered with 



glacier ice. 

 GLACIERET, GLACIERETTE: 



(1) (II.A.l.e.)— Snowdrift ice. 



(2) (II.A.l.d.)— A little glacier. 



GLACIER ICE: (I I. A.) — Ice which is formed in glaciers. 



GLACIER ICEBERG: (II.A.5.a.)— An iceberg usually bluish or green- 

 ish in color, with little or no snow cover and often containing many 

 crevasses. Such icebergs are smaller than tabular icebergs. Glacier 

 icebergs are derived from glaciers, piedmont ice, confluent ice, 

 or ice tongues afloat. See iceberg. 



GLACIERIZED: (II.B.)— Glacier covered. 



GLACIER TABLE: (II.B.)— Ice pillar. 



GLACON: (I. A. 2.) — A fragment of sea ice ranging in size from brash 

 to a medium floe. 



GLADE: (I.C.l.c.)— Polynya. 



GLASS ICE: (I.A.3.b.)— Ice crust. 



GLAZE: (V.B.) — A smooth, transparent or translucent ooating of ice 

 formed by the freezing of rain on terrestrial objects. See ice storm. 



GLIMMER ICE: (I.A.3.)— Newly-formed ice within cracks or holes 

 of older ice, or in the puddles upon older ice. 



GRANULAR ICE: 



(1) (V.B.)— Rime. 



(2) (II.B.)— Neve. 



GREASE ICE: (I.A.3.a.) — A kind of slush formed from the congelation
