Hollick: Features of Silver Lake Basin 65 



toward the deepest part of the basin, where a shallow pool of 

 water yet remains, and the constantly widening cracks and 

 crevasses form a series of irregular contours around the pool. 

 The best defined slips and faults are around the southwest end, 

 where the original floor of the basin is steepest. 



Wherever the morainal till beneath the peat is exposed this 

 presents an appearance quite unlike the characteristic red till of 

 the adjacent banks. It is of a uniform gray color, due to the 

 reduction of the red oxid of iron by the organic acids in the 

 decaying vegetation which forms the peat and organic matter in 

 the silt. Fragments of Triassic sandstone, the most abundant 

 constituent of the till, are gray on the surface, but when broken 

 show their original dark red or brown color inside. 



Incidentally it may be pertinent to remark that several cannon 

 balls, in all probability of Revolutionary age, were unearthed and 

 are now deposited in our collection of such relics. Thus far no 

 Indian relics have been brought to light, although it is certain 

 that some must have been lost within the area of the basin, 

 inasmuch as a number have been picked up in the immediate 

 vicinity, where there were indications of several old camp sites.''
