LOCAL GLACI ALTON IN CATSKILL MOUNLAINS 121 



red debris, and is overlain by several feet of red lake clay. South of 

 Devasego Falls, in the Schoharie and its tributaries, the moraines are 

 composed very largely of this local red material. (2) Moraines across 

 the Schoharie valley and its tributaries are, apparently in every case, 

 convex down-stream. This is especially well shown at Devasego 

 Falls, along the Manor Kill west of Conesville, and along the Batavia 

 Kill between Prattsville and Ashland. (3) There are lateral moraines 

 leading into these loops in a direction indicating ice-movement, out 

 from the mountains. 



SUMMARY 



The elevation and consequent low temperature of the Catskills 

 would enable them to support glaciers while the surrounding lower 

 lands were entirely deserted by the ice. In one valley at least, local 

 glaciers did exist for a period of time long enough for the build- 

 ing of a morainic loop 60 feet high in places. Evidences in the Scho- 

 harie valley point toward quite an extensive movement outward and 

 northward from the mountains.
