this area at a time when the serpen- 
tine hills were covered by the Cre- 
taceousand Tertiary sediments * * * 
As this ancient stream cut down 
through these sedimentary deposits it 
encountered the resistent serpentine, 
into which, stimulated by a consider- 
able fall due to the erosion of the 
sedimentary formations southeast of 
the serpentine hills, it cut a straight, 
narrow notchorgorge. Subsequently, 
when the land stood higher than now. 
the head waters of this hypothetical 
stream were, probably, drawnoff by 
some lateral tributary of the Hudson, 
perhaps in the line of Kill van Kull, 
‘the downward progress of which was 
not retarded at so high a level by con- 
tact with the head rocks ”’
