The York and Escrick glacial moraines swing north and merge north of Wetherby to cover the magnesian limestone with glacial deposits. In the Bedale area and northwards, these deposits are so extensive as to mask the limestone topography. South of Wetherby there is only a thin layer of glacial deposits overlying the limestone.
Geologically, Holderness is underlain by Cretaceous chalk but in most places it is so deeply buried beneath glacial deposits that it has no influence on the landscape. The landscape is dominated by deposits of till, boulder clays and glacial lake clays. These were deposited during the Devensian glaciation. The glacial deposits form a more or ...
The glacial deposits form a more or less continuous lowland plain which has some peat filled depressions (known locally as meres) which mark the presence of former lake beds. There are other glacial landscape features such as drumlin mounds, ridges and kettle holes scattered throughout the area. The well-drained glacial deposits provide fertile ...
North Sea Ice penetrated inland to leave deposits of till along the coastal margin. Newton Dale, the course of the Sea Cut and the Forge Valley are all landscape legacies of this period. Gormire Lake beneath Whitestone Cliff is of glacial origin.
A similar situation exists in east Yorkshire in the Holderness district. The chalk outcrop at Flamborough Head in the north produces a headland relatively resistant to coastal erosion whilst the coastline south of this at such places as Mappleton and Hornsea with their soft glacial deposits are vulnerable.
The Yorkshire Wildlife Trust was originally established to conserve Askham Bog. [12] The first management plan was designed to maintain habitat diversity throughout the bog. To achieve this, the National Conservation Corps was enlisted to create more open water by digging ponds and blocking dykes, along with scrub clearance in the damp cotton ...
The Great Stone of Fourstones, or the Big Stone as it is known locally, is a glacial deposit on the moorlands of Tatham Fells, England, straddling the county border [1] between North Yorkshire and Lancashire, near Bentham in the District of Craven. The name suggests that there were once four stones, but now there is only one.
These deposits include glacial till, sand and gravel and both terminal and recessional moraines left by receding ice sheets at the end of the last ice age. The Escrick moraine extends across the vale from west to east and the York moraine, 8 miles further north, forms a similar curving ridge from York eastwards to Sand Hutton.
