Glaciiil sand plains. Deposits i>f stratifieU gravel and sand in the form of deltas 

 and gently sloping fans, deposited by streams along the margin of a glacier. 

 Where built into open water, the deltas usually show fore-set beds in the 

 body of the deposit and top-set bedis capping the whole. AVhere the deposit 

 has banki'd up about the margin of the ice front, a terrace is formed by the 

 subst.M|Uc'nt melting out of the ice 



Glaciated. Said of a country which has been scoured and worn down by glacial 

 action, or strewn with ice-laid drift 



Ground nu^raine. Coating of boulders or mixture of boulders, gravel, sand, and 

 clay which a glacier leaves on the surface of a country. In existing glaciers, 

 the debris carried along under the ice 



Ice contact. Terracelike slope at the iccvard margin of deposits which have 

 l>een banked up against the ice front or about masses of ice. The slope is 

 often cost in nn)unds (kames) and hollows which result from the melting out 

 of buried masses of ice. Where smooth and even like a river terrace, it may 

 l>e distinguished from a river terrace by its position often being such that a 

 river couhl not have flowed along its base 



Ice-laid. Said of boulders, or mixtures of boulders, gravel, sand, and clav 

 which have accuinubited under a moving glacier or have come to rest on the 

 groun(^from the melting out of the ice in which the nwterial was embedded 



Ice sheet. Form of glacier moving radially outward from a region of great snow- 

 fall and covering usually all but the highest mountains in its path 



Interglacial. Interval between two glacial epochs or advances of the ice 



lutraglacial. Said of phenomena peculiar to the field actually covered by the ice 

 nt any given time; contrasted with extraglacial 



Inlerlobate. Lying between two lobes of a glacier 



Kames. Mounds of stratitied or rudely stratified gravel and sand often separated 

 by hollows; due to the irregular settling or deposition of deposits laid down 

 ill the presence of melting masses of ice 



Kame moraine. Belt of glacial deposits laid down by the interaction of ice and 

 water at or just within the margin of an ice sheet, and having the form of 

 kames 



Kaniy. Characterized by low knobs and shallow depressions (colloquialism) 



Kettle-hole, ice-block hole. Pit or depression sometimes occupied by standing 

 water; often found in glacial sand plains or other glacial deposits where 

 masses of ice liave melted out 



Lobe. One of the rounded spurs of the outward margin of a delta formed 

 where a stream has pushed its deposit out beyond the general line; also one 

 of the protrusions of ice along the margin of a glacier 



.Moraine. Swiss term for the debris transported and deposited by glaciers; in 

 America, the ice-laid drift accumulated about the edge of a glacier, usually 

 in belts ami often a mile or more in width, classified with regard to position 

 in relation to the ice as frontal, submarginal, lobate, interlobate, etc. 



Osar. Swedish term for eskers; Swedish singular os. plural osar; through mis- 

 undenjtanding, English singular osar, plural osars have been used
