REPORT OF THE DIRECTOR I918 2$ 



Comparatively little positive evidence for faulting was observed. 



Glacial striae show that the general direction of ice movement 

 during the Ice age was southwestward across the quadrangle. During 

 the withdrawal of the ice the area was widely strewn with ground 

 morainic materials containing many boulders. Much fluvioglacial 

 material was also deposited, especially on the lower lands. A very 

 conspicuous kame-moraine 12 miles long, extending from southwest 

 of Goldsmith to near Hammond school, was formed along the margin 

 of an ice-lobe which paused temporarily during its retreat from the 

 Saranac valley. Smaller kames, and at least one esker, were also 

 observed. Glacial lake waters formed at various levels during the 

 retreat of the ice, especially in the Saranac valley, as shown by well- 

 preserved delta sand plains. The gorge and waterfalls south of 

 Moffitsville are of postglacial origin, the old channel of the river 

 having been a little farther west. 



INDUSTRIAL GEOLOGY 

 BY DAVID H. NEWLAND 



Report on mineral resources. The need for a revision of previous 

 information about the mining and quarry resources of the State 

 has been emphasized during the last year or two by the many changes 

 and developments that have taken place in the several related 

 industries. It has been a time of unprecedented activity and the 

 possible scope of productive operations has been enlarged through 

 the growth of market demands for some of the staple commodities 

 and the coming into use of certain materials that hitherto were 

 regarded as of little account. Though the gains thus recorded may 

 not prove permanent additions to the industrial field, the effects 

 of the increased activity and developments will provide a stimulus 

 which can hardly be otherwise than beneficial. 



The new report is designed to serve as a general guide to the 

 subject, indicating what kinds of ores and minerals occur in sufficient 

 quantities to be of commercial interest and giving particulars of 

 their distribution and such features of their geology as have a 

 practical bearing upon their utilization. The treatment is compre- 

 hensive, but not exhaustive. In accordance with plans already in 

 force, separate monographic reports will continue to be provided 

 for the more important branches of the mining and quarry industry, 

 such as have been issued in recent years upon iron ores, pyrite, zinc, 

 building stones and other subjects of current interest.
