RECENT GLACIAL SECTIONS IN HOLDERNESS. 
T. SHEPPARD, M.SC. , F.G.S. 
With Mr. J. W. Stather, I recently visited a few sections 
in the Glacial Series between Hull and Hornsea. 
At Skir laugh, opposite the church, the road has recently 
been widened in view of the increased motor and other traffic, 
and has exposed a section in boulder clay varying from three 
to seven feet in height, which, as yet, is not grassed over. The 
clay is unusually full of pebbles, in this respect contrasting 
with the upper part of the coast sections, where the clay con- 
tains very few ; but this particularly strong feature at Skir- 
laugh is doubtless due to the inclusion in the clay of pebbles 
derived from the gravels which are so frequent to the North 
and East. Some of the contained pebbles, such as Mica Schist 
and Cheviot porphyrite, were very rotten, and could be crushed 
to powder in the hand. The usual preponderance of small 
pebbles of Cheviot porphyrite and Grauwacke (from the same 
area as the porphyrite) indicates that clay exposed is of the 
Upper or Hessle Boulder clay type. Large boulders, up to 
a foot or more in diameter, of basalt, Carboniferous limestone, 
and an occasional granite, taken from the clay, are used in 
curbing. 
As a result of the necessity for obtaining gravel locally for 
the purpose of making concrete for house-building, etc., many 
gravel pits, which had been almost or entirely neglected before 
and during the war, have recently been opened out. The 
well-known hill near Brandesburton, known as Coney Garth, 
is near to that which years ago yielded remains of mammoth, 
etc., to Clement Reid (see ‘ Geology of Holderness/ 1885,) 
has been purchased by the Beverley Corporation, and is being 
carted away. Thus, by artificial means, the Holderness 
landscape is changing ; the one time feature known as Kelsey 
Hill being now a deep hole, due to the necessities of the North 
Eastern and the Hull & Barnsley Railway Companies. 
The section exposed at Coney Garth is quite typical of 
the Holderness glacial beds, and shows current -bedded sands 
and gravels, usually well rounded, with occasional shell 
fragments, and the typical assemblage of rocks from the Lake 
Districts, the Cheviots, Scotland, Scandinavia, the bed of the 
North Sea, and the East Coast. Mammalian remains do not 
appear to have been recorded recently, excepting the ‘ skeleton 
of a monk/ which the men inform me was obtained some 
little time ago, though this gentleman, of course, was much 
later in date than the gravel beds. 
At Leven, near the road -side, an old pit has been re-opened, 
and has exposed a section eight or ten feet in height, very 
much resembling the section near Cottingham referred to in 
the Annual Report of the Yorkshire Naturalists’ Union (see 
1922 Feb. 1
