NOTES ON GLACIAL DEPOSITS NEAR PICKERING. 
BY J. T. SEWELL. 
In Professor Kendall's paper on "The Glacier Lakes of 
Cleveland " (Yorkshire Geological and Polytechnic Society, 1903), 
mention is made of the delta formed at the mouth of the 
Newton Dale valley, and he describes how it was through this 
dale that the Cleveland drainage flowed into the then existing 
" Lake Pickering." Being in Pickering a short time ago, and 
hearing of some well-sinking in the neighbourhood, I thought an 
account of the spoil, as confirmatory of the above paper, would 
be of interest to your readers. 
Well at Bever's Mill. — Situated half a mile due south of 
Pickering Railway Station ; it is 15| feet deep, and no solid rock 
was found ; this well is sunk in the lowest part of the present 
surface drainage, and directly in line with the Newton Dale 
outflow. The spoil consisted of river gravel and small stones, all 
water- worn, amongst which were embedded round and rounded 
stones varying from 2 feet to 6 inches in diameter. There was 
no clay and no earth mould, while the smaller stones were flat 
with rounded edges ; still there was a total absence of slabs of 
rock, such as are generally found in most of the local streams. 
These had evidently been broken up in their passage down the 
gorge hy the more massive boulders into pieces 2 to 4 inches 
long. 
We note the following : — 
Local Oolitic Limestone ; largely represented by coarse 
sand and small pieces of rounded stone. 
Kellaways rock in various sizes ; one piece showed the 
casts of belemnites very little worn. 
Limestone Marls. These hard rocks still retain their flat 
sides ; the edges, however, are well rounded. 
Coarse-grained sandstone, reddish. These boulders had the 
appearance of granite and were very hard, but the " shell " once 
broken were found to consist of a friable, grainy Estuarine 
series.
