GLACIAL BEDS AT HUNMANBY, E. YORKS. 
T. SHEPPARD, M.Sc., F.G.S. 
HAVING occasion recently to wait a while for a train at 
Hunmanby, near Filey, | visited Mr. Parker’s brick pit, which 
adjoins the station, and which, a few years ago yielded a 
Chariot Burial of the early Iron Age.* The section is about 300 
feet above O.D. and is almost on the line of the moraine which 
is so well developed a little further south, at Speeton. The 
pit is largely overgrown, but is being worked at one or two 
places. An examination of these shows that the deposit is very 
variable, but roughly may be taken to show :— 
Rounded Gravel, 8 feet ; 
Purple Boulder Clay, 6 to 8 feet ; 
Contorted Laminated Clay Orieet® 
and doubtless this rests on a further bed of Boulder Clay. 
In some parts of the pit, at the top of the section, there 
was a loose red earthy clay resembling Hessle Clay, though 
it may have been re-distributed. 
The gravel was typical glacial gravel such as occurs in other 
parts of the district. The purple ‘boulder clay was also typical 
of that deposit, both with regard to texture and contents. 
The stoneless laminated clay is interesting. Fallen blocks 
on being dried split into innumerable laminze resembling the 
deposit described by G. W. Lamplught in the cliff section 
south of Bridlington. Dried fragments show whitish partings 
on which are small ripple-marks. It has every appearance 
of having been deposited in a glacial lake. But it is not 
entirely in its original position, if at all. The beds are twisted 
and contorted in a remarkable manner. Besides being 
crumpled and folded, whole masses have been torn away and 
thrust along ; in some places they have evidently been heaped 
up and crushed together, now and then resembling current 
bedding, at other times taking the appearance of an enormous 
crush-breccia. The fine lines of demarcation between one 
mass and another suggest that the lumps were crushed together 
while in a frozen condition. 
This particular bed of course, though limited in extent, 
makes excellent bricks—those made from the boulder clay 
in the remainder of the section being much inferior. 
At various places in the floor of the pit are heaps of boulders, 
many, especially the limestones, being glacially striated.. These 
are no doubt principally derived from the Purple Boulder Clay, 
though a few are obviously from the gravel, and some, such as
