around to the west, while a well-characterized 

 terminal moraine, formed by the glacier to 

 wards the close of its existence, unites them 

 near their lower extremities at a height of 

 eighty-five hundred feet. Another pair of 

 older lateral moraines, belonging to a glacier 

 of which the one just mentioned was a tribu 

 tary, extend in a general northwesterly direc 

 tion nearly to the level of Big Smoky Valley, 

 about fifty-five hundred feet above sea-level. 



Four other canons, extending down the 

 eastern slopes of this grand old mountain into 

 Monito Valley, are hardly less rich in glacial 

 records, while the effects of the mountain- 

 shadows in controlling and directing the move 

 ments of the residual glaciers to which all these 

 phenomena belonged are everywhere delight 

 fully apparent in the trends of the canons 

 and ridges, and in the massive sculpture of 

 the neVe&quot; wombs at their heads. This is a very 

 marked and imposing mountain, attracting 

 the eye from a great distance. It presents a 

 smooth and gently curved outline against the 

 sky, as observed from the plains, and is whit

 summit is made up of irregular volcanic tables, 

 the most extensive of which is about two and

 is broken abruptly down on the edges by the
