GEOLOGY OF THE PARxVDOX LAKE QUADRANGLE 463 



In the Adirondacks the most important problems today belong to 

 two distinct departments of geology. One series of problems is con- 

 cerned with the physiography and glacial phenomena, on which no 

 detailed work has been hitherto done; the other series of problems 

 are concerned with the gneisses, both as to relative age and as to 



origin. 



Recent geolog^ic work 



The first geologic report on the Adirondacks was that of 

 E. Emmons in 1842. Since that time little was attempted until 

 about fifteen years ago, when Prof. J. F. Kemp took up the task of 

 unraveling the complicated structure of the eastern part of the 

 region, while Prof. C. H. Smyth jr in the west and Prof. H. P. 

 Gushing in the north directed their efforts to those portions. The 

 combined work of these three investigators has led to interesting 

 results in the interpretation of the region as a whole. 



The greater part of the region covered by the Paradox Lake 

 quadrangle was described in a preliminary way in Professor Kemp's 

 early reports.^ 



The southern portion of the region was treated by Professor 

 Kemp and D. H. Newland.^ 



The preliminary work was done without the aid of good maps, 

 and it was not thought advisable to begin detailed investigation until 

 the United States Geological Survey sheets were published. Some 

 of. these topographic maps have recently appeared, and with one of 

 them as a basis it was hoped that by a careful and detailed study 

 of a relatively small area some facts might be added to those already 

 accumulated. The purpose of this paper is to treat in detail of the 

 geology, both glacial and deep seated, of the area covered by the 

 Paradox Lake quadrangle, thus making a beginning of the interpre- 

 tation of Adirondack glacial deposits, and a contribution tO' the solu- 

 tion of the problems of the gneisses.
