At Danskammer the stream is about 3500 feet wide. The results 

 of wash borings gave a range in depths from 133.2 feet to 268.5 

 feet to supposed rock bottom, but the evident irregularity and 

 variability would seem to indicate a bed of loose material at these 

 depths at this crossing. 



At the Storm King crossing the drill brought up from a depth of 

 617.4 feet a core of granite just like that on the east bank of the 

 river, which it had penetrated to a distance of 8.8 feet. The drill 

 was thought to have reached rock bottom at this point at a depth 

 of 608.6 feet not far from 750 feet from the east bank. 



Casper creek was tested near its mouth by wash borings. The 

 lowest point thus reached was 6^ feet below tide.

In Wappinger creek one wash boring below the falls reached a 

 depth of 50 feet below tide. Of three core borings, the maximum 

 was 39 feet.

A proposed line of tiie aqueduct crossed Fishkill creek near the 

 village of Fishkill. Everything is beneath the drift at this point. 

 Of two core holes, the deeper reached the limestone at 40 feet below 

 tide. After penetrating 8 feet of limestone, the drill encountered 

 fine yellow sand in which it continued for 60 feet, when the hole 

 was abandoned. This crossing is about five miles back from the 

 Hudson.
