GLO.SSARY 



Terms used in this bulletin or found in writings concerning glacial phenomena 



Aggradation, aggrading. Deposition of alluvial plains by streams 

 Horrow-pit. Pit from which gravel or sand is taken in construction work 

 Boulder belt. E.xtended pile of boulders accumulated in the form of a frontal 

 moraine; or excessively bouldery ground marking the former po^^ition of the 

 front of an ice sheet 

 Boulder train. Term applied in the United States to the train of boulders and 

 pebbles distributed by the ice sheet over the countr}' .southward of some 

 readily ideiititied rock having a limited e.xposure in the glaciated field and 

 of wliich the boulders an<l pebbles consist 

 Col. That part of a divide which lies in a pass 



Columbia formation. Series of loams, gravels, and sands oeeurriii^^ in tlie coastal 

 plain, forming terraces and river deltas deposited during the submergence of 

 the land before the bist or Wisconsin glacial epoch and after the tertiary. 

 The deposits are variously subdivided in New Jersey and Maryland. The 

 cojirseness of some of the deposits indicates a p(;riod of cold with signs of 

 glaciation and one or more advances of the ice over the glaciated district
