GENERAL MAP OF THE GLACIERS AXD GLACIRR-LAKES OF THE CLEVELND AREA, 



AT THE PERIOD OF MAXIMUM EXTENSION OF THE ICE. 



Reduced, by kind permUsion, from Map published in the Quarterly Journal of the Geological Society. 



The Block kindly lent by the Editor of The Friend. 

 The area covered by ice is left uushaded ; the lakes are indicated by marginal shading ; and the area 

 occupied neither by ice nor by lakes is crossed-hatched, to show the relief of the land. The edge of the 

 ice is indicated by a heavy black line. Broken lines are used upon the south and west, as the marginal 

 phenomena have not yet been studied.
